Abstract: A wireless communication device employs a method for receiving a message stream on a control channel. According to one embodiment, the wireless communication device receives a message on the control channel. The wireless communication devices attempts to decode the message and, if the message is successfully decoded, adds bits of the successfully decoded message to a message attributes list. Some time thereafter, the wireless communication device attempts to decode a subsequent message received on the control channel and, if an error is detected during decoding of the subsequent message, replaces bits in the subsequent message with bits from the message attributes list to produce a modified message. The wireless device then attempts to decode the modified message.

Abstract: A method is provided for determining a residual charge on a battery (12), comprising applying a discharge pulse to the battery (12) and measuring a first voltage on the battery (12) at a first time (t1). Additional voltages on the battery are measured at additional times (t2, t3) subsequent to the first time (t1). Delta voltages (?V1, ?V2) are determined by subtracting each of the additional voltages from the first voltage and delta times (?t1, ?t2) are determined by subtracting the first time from each of the additional times. Regression equation coefficients (?, ?) are determined from regression analysis of the delta voltages and delta times, and are applied to a database for determining the residual charge.

Abstract: A liquid crystal device comprises a cholesteric liquid crystal material interposed between a transparent front plate and a back plate. The cholesteric liquid crystal material is switchable between a transparent state and a reflective state in response to an electric field applied in a first direction. In the reflective state the material reflects light characterized by a first wavelength when no electric field is applied. Electrodes are provided for applying an electric field lied to the cholesteric liquid crystal material in the reflective state in a second direction distinct from the first direction. In this manner the cholesteric liquid crystal material is altered to cause the material to reflect light characterized by a second wavelength different from the first wavelength. A display device may thus be produced having pixels capable of a wide range of colors, thereby achieving a multicolored image for the display.
