Abstract: A sensor for physiology sensing may be configured to generate oscillation signals for emitting radio frequency pulses for range gated sensing. The sensor may include a radio frequency transmitter configured to emit the pulses and a receiver configured to receive reflected ones of the emitted radio frequency pulses. The received pulses may be processed to detect physiology characteristics such as motion, sleep, respiration and/or heartbeat. In some embodiments, the sensor may employ a circuit including a pulse generator configured to generate signal pulses. The circuit may also include a dielectric resonator oscillator configured to generate a radio frequency oscillating signal. A switched oscillation circuit may be coupled to the pulse generator and the dielectric resonator oscillator. The switched circuit may be configured to generate a pulsed radio frequency oscillating signal for emitting the radio frequency pulses.

Abstract: A calf chute tailgate particularly suited for use in calf roping competitions is disclosed. The tailgate has a pair of upright bars that are mounted to the entry of the calf chute using a pair of four-bar linkages so that during opening and closing of the gate the bars retain their upright orientation resulting a calf chute gate that is fully open across its full height permitting easy access to the chute by calves of any size and shape.

Abstract: An internal combustion engine (100) includes a turbocharger having a turbine (108) and a compressor (118) with an air inlet (120) and a charge air outlet (119). An electronic actuator (200) has an internal cavity (226). An intake manifold (104) is in fluid communication with the charge air outlet (119) of the compressor (118) through a cooled charge air passage (126). A bleed air passage (136) fluidly connects the cooled charge air passage (126), at a bleed air point (134), with the internal cavity (226) of the electronic actuator (200).

Abstract: A turbocharger (300) for an internal combustion engine (500) includes a center housing (304) connected to a turbine housing (302) and a compressor housing (306). A shaft (318) is in a bore (314) of the center housing (304). An oil supply passage (328) is in fluid communication with the bore (314). An oil drain passage (310) is in fluid communication with a oil cavity (334) and the bore (314). A vent passage (330) is in fluid communication with the oil cavity (334) and an internal volume (520) of the internal combustion engine (500). Oil flow passes through the first passage (328) and the drain passage (310) during operation of the internal combustion engine (500). A first pressure of air (P1) in the oil cavity (334) is about equal to a second pressure of air (P2) in the internal volume (520) of the internal combustion engine (500).
