Abstract: In one illustrative example, a vehicular flasher unit is operative to provide a heartbeat flasher scheme in vehicle flasher lights. One illustrative technique in the vehicular flasher unit involves monitoring a flasher enable input to identify a flasher enable signal and producing, at a light illumination output in response to identifying the flasher enable signal, a heartbeat flashing scheme in the vehicle flasher lights. The heartbeat flashing scheme has a repeating sequence of two heartbeat pulse flashes in the vehicle flasher lights which include a first heartbeat pulse flash and a second heartbeat flash. Each first heartbeat pulse flash has a first peak intensity in the vehicle flasher lights and each second heartbeat pulse flash has a second peak intensity in the vehicle flasher lights that is preferably different from the first peak intensity.

Abstract: In one illustrative example, a vehicular flasher unit has control circuitry; memory which is accessible by the control circuitry and having a plurality of pulse width modulation (PWM) flasher scheme data sets stored therein which correspond to a plurality of flasher schemes for vehicle flasher lights of a vehicle; a flasher scheme selection input to the control circuitry; a flasher enable input to the control circuitry which enables a flasher scheme in the vehicular flasher lights; and a light illumination output from the control circuitry which controls illumination of the vehicle flasher lights.

Abstract: A cordless telephone-to-sound card interface adapter provides a connection between any standard cordless telephone system and a sound card of a computer for PC-to-PC or PC-to-telephone voice communications over the Internet. The interface adapter includes a hybrid transformer circuit for interfacing a two-wire circuit of the cordless telephone and a four-wire circuit of the computer sound card. Consisting of passive components, this hybrid transformer circuit cancels out the voice echo that would otherwise exist due to mismatched impedances between the two media and/or from leakage of the signal being transmitted and received on the same pair of telephone lines. Preferably, a Universal Serial Bus (USB) interface is provided to supply a bias voltage to the cordless telephone system through the interface adapter.
