Infusion device and driving mechanism for same

A drive mechanism for delivery of infusion medium a coil capable of being electrically activated to provide an electromagnetic field. The coil surrounds a piston channel extending in an axial direction. The piston channel provides a passage for communication of infusion medium to an outlet chamber located at one end of the piston channel. An armature is located adjacent the coil, on one side of the axial channel. The armature is moveable toward a forward position, in response to the electromagnetic field produced by activation of the coil. A piston is located within the piston channel and is moveable axially within the channel to a forward position, in response to movement of the armature to its forward position. The armature and piston are moved toward a retracted position, when the coil is not energized. In the retracted position of the piston, a piston chamber is formed between the piston and a valve member and is filled with infusion medium. As the piston is moved to its forward position, the piston chamber volume is reduced and pressure within the piston chamber increases to a point where the pressure moves the valve member into an open position. When the valve member is in the open position, medium from the piston chamber is discharged into an outlet chamber located on the opposite side of the coil relative to the armature. An outlet is provided in flow communication with the outlet chamber, for discharging infusion medium from the outlet chamber.

Power Supply Controller

A power supply controller controls the output of a DC / DC converter, so that the power output can be used not only by an electrical power steering apparatus, but by other operating / driving controllers as well. The controller may command the DC / DC converter to reduce the voltage of the high-voltage battery to a prescribed voltage or to boost the voltage of the low-voltage battery to a prescribed voltage when appropriate. In addition, the controller may also command the gradual reduction of the power supplied by the DC / DC converter to the power steering apparatus. The gradual reduction in power prevents a sudden change in the steering feel, which improves drivability of the vehicle.

Distributed Out-of-Band (OOB) OS-Independent Platform Management

A system and method is disclosed for a distributed out-of-band (OOB) management controller system enabling efficient usage of power while providing multiple methods and levels of communication between intelligent devices. Two or more management controllers collaboratively operate in a predetermined manner including, but not limited to, peer-to-peer, master / slave, or independently. Management information consistency is maintained across a system's power states by implementing distributed intelligent devices that directly interact as communication devices to local or remote management consoles. A management protocol is implemented such that management information is communicated between managed elements and management controllers over physical interfaces or via a network connection. A first management controller is implemented to communicate with managed elements via a bus that is available only when the system is under full power and a second controller is implemented to communicate with the same managed elements for most power states, including low power. The second management controller remains operable to generate simple management information packets or use packets stored in communications devices to generate primitive or higher-level alert functions.

Multi-compliance voltage generator in a multichannel current stimulator

An improved multi-voltage power supply charges individual small capacitors to different voltages. Each small capacitor is assigned to a circuit, and is charged to a voltage level sufficient for the circuit. In one embodiment, an improved switching regulator includes a multiplicity of small capacitors. The small capacitors are assigned to stimulation channels of a stimulation system. Each channel has a unique compliance voltage which the assigned small capacitors are charged to. By charging the small capacitors to the corresponding compliance voltages, versus charging a single large capacitor to the maximum compliance voltage, unnecessary power dissipation is avoided. In another embodiment, a switched capacitor power supply benefits from the present invention in the same manner as the switching regulator power supply. Further, any system requiring a plurality of different voltages may benefit from the present invention.

Charging methods for battery powered devices

A battery charge control system including an algorithm for determining whether the battery chemistry of a battery pack for use in a portable electronic device is primary, in which case charging is prevented, or secondary, in which case charging is enabled. The routine operates by measuring the terminal voltage and temperature of the battery under certain predetermined tests, which generally include a combination of voltage and internal impedance tests performed during charge or discharge. Additionally, a method is described to detect and to correct for lack of cell balance within the rechargeable battery pack of a portable electronic device. A cell or cells of the battery pack which are close to depletion, or are completely depleted, are detected, and a discharge / charge routine is executed to provide for optimum recharging of all of the cells of the battery, thus ensuring proper cell balance, and most efficient power usage.

Multi-carrier modulation with source information allocated over variable quality communication channel

A multi-carrier communication system (400) groups subchannels (802) into different quality-of-signal (QoS) regions (804). An unconstrained optimization process (1200) is performed independently for the subchannels (802) of the different QoS regions (804) to allocate bit rates and power to the individual subchannels (802) so that the indicated QoS will result. Coders (504, 508, 512, 516) partition and error-correction encode source information using encoding schemes matched to the different QoS regions (804). A set (1100) of only a few directed QoS partition vectors (1102) direct the unconstrained optimization process (1200) to attempt bit-rate and power allocations on only a few promising groupings of subchannels (802) and QoS regions (804). An iterative process may take place between bit-rate and power allocation on one side and source information coding on the other for different directed QoS partition vectors (1102) to identify the best solution.

Method for cooking a food with infrared radiant heat

An oven using radiant heat at infrared wavelengths optimized for producing rapid and uniform cooking of a wide variety of foods. The infrared oven toasts, bakes, broils, and reheats food at a much faster speed while maintaining high quality in taste and appearance of the cooked food. Optimal infrared wavelengths of the radiant heat sources are used for the best balance of cooking performance, while also reducing the time required to cook the food. Typically short to medium wavelength infrared radiant energy will result in good performance for toasting and browning of food. Medium to long wavelength infrared radiant energy is well suited for delivering more deeply penetrating radiant energy into the food. This deep penetration of radiant infrared heat energy results in a more thorough internal cooking of the food than with conventional methods of conduction and convection cooking.
