Abstract:
A vapor compression system having a defrost cycle is disclosed. A compressor, a condenser, an evaporator, and an expansion valve connected in a closed refrigerant loop with at least one flow control device. The at least one flow control device may control the flow of refrigerant through the closed refrigerant loop. At least one sensor monitors a predetermined parameter of the closed refrigerant loop and at least one controller receives a signal from the at least one sensor. The at least one controller controls the position of the at least one flow control device. The at least one controller initiates a defrost cycle in the closed refrigerant loop by substantially actuating at least one of the at least one flow control device to provide refrigerant flow from the compressor to the evaporator for substantially preventing formation of frost on the evaporator.
Abstract:
Methods and systems to enable touch-free call origination using a communication device equipped with a microphone. The method comprises processing a first microphone signal at the device in an attempt to detect a spoken activation command potentially contained therein. Responsive to detection of a spoken activation command in the first microphone signal, the method continues by establishing a communication path between the device and a network entity to convey to the network entity a second microphone signal. Finally, the method comprises processing the second microphone signal at the network entity in an attempt to detect a call origination command potentially contained therein; and, responsive to detection of a call origination command in the second microphone signal, attempting establishment of a call in accordance with the detected call origination command. Thus, a call can be established without tactile interaction with the device and, moreover, with minimal computational load on the device.

The battery charger also includes a charging circuit supported by the housing and electrically connectable to a power source and a battery port positioned on the first surface. The first and second extended side portions extend beyond the battery port.
Abstract:
In an industrial control configuration, various instances can exist that are based upon a definition. A definition can be changed and thus it can be appropriate to alter related instances in accordance with the change. However, changing an instance can cause disruption in other actions even when the change is minor. Therefore, various standards can be used to determine if a change to an instance should be propagated automatically or at another time, such as after an operation. The determination can be based on artificial intelligence techniques, user preference, a defined rule set, user instruction, as well as other standards.
Abstract:
A method of animating feather elements includes: specifying initial positions for a skin surface and for feather elements; specifying positions for the skin surface at an animated time; determining a feather-ordering sequence for placing the feather elements on the skin surface; determining positions for skirt elements that provide spatial extensions for the skin surface at the animated time; determining positions for feather-proxy elements that provide spatial extensions for the feather elements at the animated time; and determining positions for the feather elements at the animated time by extracting the feather elements from the feather-proxy elements. The feather-proxy elements are determined from the skirt elements according to the feather-ordering sequence, and the feather-proxy elements satisfy a separation criterion for avoiding intersections between the feather-proxy elements.
Abstract:
A system for enabling a user of a communication device to both handle an incoming call and originate an outgoing call without having to touch the communication device, by way of exchange of voice messages with the communication device. The system is operative for receiving a signal produced by a microphone associated with the communication device and for processing this signal in an attempt to detect at least one of a plurality of spoken commands potentially contained therein. The plurality of spoken commands comprises at least one spoken call handling command and at least one spoken call origination command. In response to detecting a spoken call handling command, the system causes handling of an incoming call destined for the communication device in accordance with the detected spoken call handling command. In response to detecting a spoken call origination command, the system causes an attempt to establish an outgoing call using the communication device in accordance with the detected spoken call origination command.
Abstract:
A brake system control method for use in a vehicle in which wheel speed normalization factors are iteratively updated, comprising the steps of: monitoring a plurality of wheel speed signals from a plurality of wheel speed sensors; determining for each wheel a wheel acceleration responsive to the wheel speed signal; determining an acceleration dead band for each wheel, wherein the acceleration dead band is proportional to a measure of vehicle acceleration; comparing the wheel acceleration to the dead band; and if the magnitude of the wheel acceleration is greater than the magnitude of the dead band, inhibiting update of the normalization factors.
