Method and calculations determine an individual's, or several individuals' simultaneous rates of oxygen consumption, maximum rates of oxygen consumption, heart rates, calorie expenditures, and METS (multiples of metabolic resting rate) in order to determine the amounts of work that is performed by the individual's body. A heart monitor measures the heart rate, and an accelerometer measures the acceleration of the body along one or more axes. An altimeter measures change in altitude, a glucose monitor measures glucose in tissue and blood, and thermometers, thermistors, or thermocouples measure body temperature. Data including body fat and blood pressure measurements are stored locally and transferred to a processor for calculation of the rate of physiological energy expenditure. Certain cardiovascular parameters are mathematically determined. Comparison of each axis response to the individual's moment can be used to identify the type of activity performed and the information may be used to accurately calculate total energy expenditure for each physical activity. Energy expenditure may be calculated by assigning a separate proportionality coefficient to each axis and tabulating the resulting filtered dynamic acceleration over time, or by comparison with previously predetermined expenditures for each activity type. A comparison of total energy expenditure from the current activity is compared with expenditure from a previous activity, or with a baseline expenditure rate to assess the level of current expenditure. A measure of the individual's cardio-vascular health may be obtained by monitoring the heart's responses to various types of activity and to total energy expended.

Coding within noisy communications channels is essential but a theoretical maximum rate defines the rate at which information can be reliably transmitted on this noisy channel. Capacity-achieving codes with an explicit construction eluded researchers until polar codes were proposed. However, whilst asymptotically reaching channel capacity these require increasing code lengths, and hence increasingly complex hardware implementations. It would be beneficial to address architectures and decoding processes to reduce polar code decoder complexity both in terms of the number of processing elements required, but also the number of memory elements and the number of steps required to decode a codeword. Beneficially architectures and design methodologies established by the inventors address such issues whilst reducing overall complexity as well as providing methodologies for adjusting decoder design based upon requirements including, but not limited to, cost (e.g. through die area) and speed (e.g. through latency, number of cycles, number of elements etc).

A system for displaying an electronic representation of the consumption of a resource by a device comprises a communication network, a database, and visual display. The database is accessible by an information processor of the network and stores information including a maximum rated amount of the resource consumed by the at least one device and the actual amount of the resource consumed by the at least one device. The visual display provides an electronic representation of the resource, the amount of the resource consumed by the at least one device and the amount of the resource saved as a function of the electronic device information, wherein the visual display presents the electronic representation in a graphical format. The graphical format of the electronic representation is a graph formatted with a range of values and an indicator of an indicated value in the range. The range of values is operable to dynamically change when the consumption of the resource by the at least one device exceeds the maximum rated amount of the resource consumed by the at least one device.

The computing device receives an electronic representation of the patient's teeth in their initial position and an electronic representation of the teeth a final position for each tooth. A route each tooth will travel to reach its final position is determined, and the teeth are scheduled to move according to a movement pattern. Moreover, the schedule of movement takes into account a maximum rate of tooth movement for each tooth, the path of movement for each tooth, the distance each tooth needs to move, any needed tooth staggering, any needed round-tripping or tooth movement slowing. The invention also includes techniques for determining an optimum number of stages for the treatment based on the schedule of movement.

A wireless terminal receives an uplink traffic channel segment assignment including a maximum uplink rate option indicator. Each uplink rate option corresponds to a number of information bits, coding rate and modulation method. The maximum rate option indicator indicates the highest rate option that the wireless terminal is permitted to use when transmitting in the assigned traffic channel segment from the perspective of the base station. In some embodiments, the wireless terminal uses interference measurements to further quality, e.g., conditionally reduce, the maximum uplink rate option that may be used. Then, the wireless terminal selects an uplink rate option to use which is less than the determined allowed maximum uplink rate option, e.g., based on the amount of user data to communicate. The wireless terminal transmits data in the assigned uplink traffic channel segment in accordance with the wireless terminal selected uplink rate.

It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

A power tong system is used to make up and break out threaded pipe connections. Rotary power tongs are connected to an integral backup tong through an extendable hydraulic cylinder and rod. A brake is secured to the rotary tong to selectively hold the pipe stationary relative to the rotary tong. When rotation of the pipe by the rotary tong ceases, the brake is applied, and the cylinder and rod are actuated to angularly displace the power tongs and the backup tong to apply a torque force to the pipe connection disposed between the power tongs and the backup. A resulting torque force is obtained that is greater than the maximum torque that can be exerted by the rotary tong acting alone. The system may also be deployed to apply and hold precise torque forces on the pipe connections. When used to obtain a makeup torque below the maximum rated rotary tong output, the rotary tong is regulated to limit its torque output. When the limited torque is reached, the brake is applied and the cylinder and rod are actuated to apply a smooth, closely controlled increase in torque to the connection. The final torque level may be held constant for a desired length of time. In both the high and low torque applications, the brake prevents the rotary tong from being turned backwardly by the increased torque force applied by actuation of the rod and cylinder assembly. Operation of the system may be manually or automatically controlled.

A fast transition power supply comprises three control functions, one to maintain steady state conditions, a voltage transition circuit that rapidly changes the charge on the output capacitor to effect a rapid step change in the output voltage, and a current control circuit that can switch a constant current in a pulse width modulation control from zero (or negative) current to any current less than the maximum rated current with no change of current in the inductors of the circuit. The power supply can thus go from zero volts, no current to full output voltage, full current very quickly, in the order of less than an micro-second. It can also transition from full voltage, full current to zero voltage, zero current just as fast, or transition from one voltage to another.

The invention provides a variable speed hydraulic pump designed to operate at a maximum horsepower throughout its pressure range by adjusting motor speed according to motor load parameters. In particular, the variable speed hydraulic pump includes a hydraulic pump unit coupled to a variable speed electric motor by a drive unit and to a hydraulic fluid tank for pressurizing and pumping hydraulic fluid when operated by the motor. A motor controller is electrically connected to the motor to supply drive signals to the motor based on electrical characteristics of the drive signals which are dependent on the load exerted on the motor. Suction from the load is provided by both the main pump and a bidirectional supercharging pump by reversing the direction of the motor and shifting a 4/3 valve to connect the main pump inlet to the load and its outlet to tank. In addition, the controller reduces the motor speed at the maximum rated pressure to just maintain the pressure, to reduce the amount of fluid pumped through the maximum pressure relief valve.

A method and apparatus for establishing traffic priorities in an IP network connected with multiple communication sources is disclosed. Different types of packets such as voice packets and data packets are received for transmission over a single network access link. In order to assure quality voice transmissions, voice packets are given priority over data packets by limiting a transmission rate from a data input queue whenever voice packets are detected in a voice input queue. Different combinations of interleaved voice and data packets help to alleviate packet congestion while maintaining priority for voice packets. In one aspect of the invention, priority for voice packets is further accomplished by limiting the size of data packet frames. In some instances when no voice packets are awaiting transmission, data packets are transmitted at a maximum rate in order to make full use of the network access link bandwidth. The invention is particularly beneficial when implemented over cable and DSL network access links with slow upstream feed rates.

A system, method and program product for managing e-mails from a source suspected of sending spam. The e-mails are received at a firewall or router en route to a mail server. A determination is made whether a source has sent an e-mail which exhibits characteristics of spam. In response, subsequent e-mails from the source destined for the mail server are rate-limiting at the firewall or router such that the firewall or router limits a rate at which the subsequent e-mails are forwarded from the firewall or router to the mail server. The rate is predetermined and less than a maximum rate at which the firewall or router can physically forward e-mails to the mail server absent the rate limit. A determination is made whether another source has sent another e-mail which exhibits more characteristics of spam than the first said e-mail. In response, subsequent e-mails from this other source are blocked at the firewall or router. The rate limit can be a limit on a number of e-mails per unit of time from the source that will be forwarded from the firewall or router to the mail server.

This document discusses, among other things, systems, devices, and methods measure an impedance and, in response, adjust an atrioventricular (AV) delay or other cardiac resynchronization therapy (CRT) parameter that synchronizes left and right ventricular contractions. A first example uses parameterizes a first ventricular volume against a second ventricular volume during a cardiac cycle, using a loop area to create a synchronization fraction (SF). The CRT parameter is adjusted in closed-loop fashion to increase the SF. A second example measures a septal-freewall phase difference (PD), and adjusts a CRT parameter to decrease the PD. A third example measures a peak-to-peak volume or maximum rate of change in ventricular volume, and adjusts a CRT parameter to increase the peak-to-peak volume or maximum rate of change in the ventricular volume.

A system and method of controlling a data rate of a user equipment (UE) for a packet data service in a mobile communication system is provided. In the system and method, a radio access bearer (RAB) assignment request message comprising maximum rate information is received. The maximum rate information indicates a requested data rate for the packet data service. An initial data rate is set to the requested data rate, and it is determined whether the initial data rate is available by checking available resources. If the initial data rate is not available, it is determined whether the initial data rate is the lowest of a plurality of levels of predetermined data rates. If the initial data rate is the lowest level, a RAB is established in a common channel state. If the initial data rate is available, a RAB is established at the initial data rate in a dedicated channel state.

A method for determining the reverse link data Rate Limit for mobile stations active on the reverse link of a High Data Rate system is disclosed. In the ideal case, the Rate Limit is based on only the number of mobile stations located in a common sector that are actually active on the reverse link. Currently, the Rate Limit is determined from the total number of mobile stations in a common sector where the total includes mobiles that are transmitting and receiving. Thus, the current method includes mobile stations that are active on the forward link and may not be active on the reverse link. In this invention, a more optimum method of estimating the reverse link loading is obtained from calculations which includes only the mobile stations which are active on the reverse link. An estimate of the reverse link loading of the mobile stations in a common cell is obtained by adding together the data rates of the data sent from each mobile in a common sector during a common frame. This aggregate rate of data during the frame is filtered to minimize irregularities by using the moving average of an infinite impulse response filter and then normalized. The normalized result is a percentage of the maximum achievable aggregate reverse link rate. The final result is compared with a set of threshold values to obtain the maximum Rate Limit that is then set for each mobile station.

The puncture sequences are groups of one or more memory elements, each of which is a variable degree, a variable node location, a check degree, or a check node location. A method for deriving such a puncture sequence for variable code rates is also disclosed.
