Abstract:

A battery detect circuit ( ) is provided that is operable to dispose a sense resistor ( ) in series with the battery to determine whether the charge is being provided to the battery or being extracted from the battery. The voltage across the sensor resistor ( ) is sensed by a voltage/frequency converter ( ). The voltage/frequency converter ( ) is a differential structure comprised of two integrator structures ( ) and ( ) that are operable to utilize a switched capacitor configuration to drive comparators on the output thereof. Each of the integrator structures ( ) and ( ) has associated therewith passive elements and active elements. The integrators ( ) and ( ) have associated therewith integration capacitors ( ) and ( ). Additionally, there are two operational amplifiers ( ) and ( ) that provide the active components of each of the integrators ( ) and ( ). The various switched capacitor circuits ( ) and ( ) associated with the amplifiers ( ) and ( ) are provided to provide the integration operation.

Abstract:

A telepresence conferencing system is disclosed in which scheduling and resource and personnel reservations may be made across various entities (i.e.; domains). Additionally, each location that is part of the telepresence conference may selectively, and independently of the other locations, designate all or selected portions of its media stream be carried over a different network from the one used to setup, control, and reserve resources for the telepresence conference.

Abstract:

A battery charging system is provided which is comprised of a battery pack (30) and a charging system (20). The battery pack (30) includes a battery (10) and a battery capacity detect circuit (32). The battery capacity detect circuit (32) is interfaced with the charging system (20) through a single line to output a CHG-Bar signal. The battery capacity detect circuit (32) is operable to perform numerous monitoring operations on the battery by detecting the charge input to the battery and detecting charge taken away from the battery in a discharge operation. This operation is performed independent of the charging operation by the charging system (20). However, the charging operation of the charger (22) can be affected with the CHG-Bar signal.

US Classification:

11212111

Abstract:

A programmable industrial sewing machine adapted to learn and store a series of sewing machine operations for later automatic duplication, in an Automatic Sew Mode of operation, at the same sewing rate as the initial operation, or at a peak sewing rate achieved during each operation; or, in a Control Sew Mode of operation at a controlled lower sew speed. The automatic operation of the sewing machine may be interrupted in order to vary the sew speed, and will revert to automatic operation on operator command where the interruption took place. In the Automatic Sew Mode of operation, stitching may also be interrupted to vary a prior pivot delay time, i. e. a time duration with the presser foot elevated and the sewing needle in a lowered position through a work material. Again, stitching will be reinitiated on operator command at the point at which interrupted. In the Control Sew Mode of operation, stitching is interrupted at each pivot delay and requires manipulation of a foot treadle by an operator in order to resume stitching.

US Classification:

Abstract:

A battery detect circuit (32) is connected to the battery with the current input to the battery and extracted from the battery measured with a sense resistor (50) and then converted to charge and discharge pulses with a V/F converter (52). A microcontroller (64) is operable to increment a Nominal Available Charge (NAC) register (180) during a charge operation, and to increment a Discharge Count Register (DCR) (184) during a discharge operation. The NAC register (180) indicates the available charge, which value is output to a display (34). The maximum value to which the NAC value can rise is limited by a value stored in the last measured discharge register (182). This value represents the value stored in the DCR (184) whenever the battery is discharged from an apparent full state to a fully discharged state. This results in a qualified transfer to the LMD register (182) such that no knowledge of the actual battery charge is necessary. The microcontroller (64) is operable to determine the rate of discharge corresponding to the voltage across the sense resistor (50).
