Devices, systems and methods are provided for simultaneously stimulating the spinal anatomy at various locations, such as spinal levels, along the spinal cord. By stimulating multiple levels of the spinal column with the use of a single device, a single access path is created to an implantable pulse generator (IPG) rather than individual access paths for each lead at each spinal level to an IPG. By reducing the number of pathways, the procedure complexity, time and recovery are reduced. In addition, some embodiments provide additional specificity within each targeted level, such as selective stimulation of specific tissue, such as the dorsal root ganglion.

A user's personal biometric information such as age, sex, weight, height as well as the user's lifestyle information, such as daily caloric input, job description, smoker status and physical fitness, is uploaded onto a host computer. Target heart rate, energy and/or caloric consumption levels related to desired fitness and weight loss goals for a particular individual are then selected having regard to fitness levels for an individual of comparable age, and consuming similar calories are then downloaded to a caloric monitoring unit. The caloric monitoring unit is provided for measuring the user's heart rate and dynamic energy and/or caloric expenditure over one to four weeks. The caloric monitoring unit includes a heart rate monitor, a unit accelerometer, a global positioning system (GPS), and an audio and/or video output. The audio/video output is operable to provide information and/or motivational prompts to the user in the event the heart rate, energy expenditure and/or caloric expenditure falls below or exceeds pre-selected target expenditures over a particular time segment of the selected time period having regard to the calories which are consumed. A display provides a continuously updated visual indication of whether or not the use has achieved the pre-selected optimum caloric burn or energy expenditure for that particular time segment. An internal calendar/clock, a processor and/or memory in the caloric monitoring unit compares measured heart rate and energy expenditures for multiple time segments against target levels stored as the user-specific fitness programme tailored to achieve the desired weight loss. The comparison is then used to generate compliance output data to either the user and/or a nutritionist.

The present technology provides adaptive noise reduction of an acoustic signal using a sophisticated level of control to balance the tradeoff between speech loss distortion and noise reduction. The energy level of a noise component in a sub-band signal of the acoustic signal is reduced based on an estimated signal-to-noise ratio of the sub-band signal, and further on an estimated threshold level of speech distortion in the sub-band signal. In embodiments, the energy level of the noise component in the sub-band signal may be reduced to no less than a residual noise target level. Such a target level may be defined as a level at which the noise component ceases to be perceptible.

A gain controller and method for controlling the value of a gain is used in conjunction with an electrode array for detecting a signal representative of respiratory drive output of a patient during inspiration, and a lung ventilator for assisting inspiration of the patient. The gain controller comprises an input for receiving the signal representative of respiratory drive output; a comparator for determining whether the signal representative of respiratory drive output is higher or lower than a target drive signal; and a gain adjustment unit for increasing the value of a gain when the amplitude of the signal representative of respiratory drive output is higher than the amplitude of the target drive signal and for decreasing the value of this gain when the amplitude of the signal representative of respiratory drive output is lower than the amplitude of the target drive signal. The gain is applied to the signal representative of respiratory drive output to produce an amplified respiratory drive output representative signal used for controlling the lung ventilator. The advantage of target drive ventilation is that this mode of ventilation does not depend on pressure, flow or volume measurements. A leaky ventilatory line will introduce a change in respiratory drive which will change the ventilatory assist in order to return the respiratory drive to its target level. Also, changes in the patient's metabolic or patho-physiological status which result in altered respiratory drive will be compensated.

A policy engine generates configlets that are vendor-neutral, vendor-specific or both, based on a selected target level and a selected device/device group. A translator translates and combines the configlets to form vendor-dependent configuration files. The policy engine generates the configlets using policies associated with the selected target level and its sub-target levels, as defined by a target level hierarchy. A policy includes at least a condition, and an action which the policy engine performs if the condition is true. In performing the action, the policy engine typically writes to at least a partial configlet. A policy may further include a verification clause, which is used to verify a running configuration. Policy dependencies may also be defined such that where a second policy is dependent on a first policy, the second policy must be evaluated after the first policy. This is necessary, where, for example, the first policy generates and stores a value to be used by the second policy. Policies are small programs written as small programs. A configlet hierarchy is defined, such that a child configlet inherits properties which it does not define from its parent. A mapping function maps infrastructure data in a first format to a second format, so that the second format is recognizable by the policy engine. A loader batches, schedules and loads a configuration file to its intended device. Upon replacing a first device using a first configuration format with a second device using a second configuration format, the first device's configuration is read in or uploaded and reverse-translated into configlets. The configlets are then translated into a configuration formatted for the second device. The system retains device logins and passwords in encrypted format. A user desiring to connect to a device must log in to the system instead. The system in turn logs in or connects to the device and passes information back and forth between the user and the device, as if the user were logged directly into the device.

An interconnect structure and method of communicating messages on the interconnect structure assists high priority messages to travel through the interconnect structure at a faster rate than normal or low priority messages.

A boost quantity detecting section (103) detects a boost quantity of an inductor (L11). An operational amplifier (113) of a control section (106) compares the boost quantity detected by the boost quantity detecting section (103) with a reference voltage (ES12). When a supply voltage supplied from an AC power source (100) reduces and an output voltage is unchanged, the boost quantity detected by the boost quantity detecting section (103) increases. When a signal level of a boost quantity detection signal is higher than the reference voltage (ES12), a control section (106) reduces a target level of a switching current. The target level of the switching current decreases, so that the output voltage decreases and energy loss due to boosting reduces.
