  • Publication number: 20180135706
    Abstract: A clutch includes inner and outer races, each with pluralities of teeth. A pawl is supported on the inner race and a shift ring disposed outward of the pawl defines pawl engagement surfaces on an inner perimeter. Pins engage cam surfaces formed in the ring and outer race. When the inner race rotates faster than the outer race, the pawl engages the ring causing relative movement between the ring and outer race that moves the pins radially inward along the cam surfaces to locate the pins between corresponding teeth on the races and rotatably couple the races. When the outer race rotates faster than the inner race, the ring moves relative to the outer race and the pins move radially outward along the cam surfaces away from the corresponding teeth to uncouple the races, disengage the ring from the pawl and allow the outer race to overrun the inner race.

  • Publication number: 20150366474
    Abstract: A system and method for measuring a subject's blood pressure is provided. The system includes a sphygmomanometer cuff configured to apply a pressure to a blood vessel region so as to restrict the flow of blood through a blood vessel of the region; at least one transducer configured to transmit a signal toward the region and to detect a return signal indicative of a velocity of blood flow through the blood vessel; and an apparatus having a processor configured to determine a systolic blood pressure of the subject. The processor is configured to determine whether the return signal corresponds to a first Korotkoff sound of the blood flow through the blood vessel, reduce pressure applied via the sphygmomanometer cuff if the return signal does not correspond to the first Korotkoff sound, and determine pressure applied via the sphygmomanometer cuff when the return signal corresponds to the first Korotkoff sound.

  • Publication number: 20140293753
    Abstract: A smartphone or other portable electronic device is operative to unlock and lock a vehicle without the use of the cellular or Wi-Fi network or any additional hardware added to the portable unit. The system, which is configured for use with a vehicle having an existing receiver to receive remote keyless entry (RKE) codes, includes a vehicle-mounted unit with a microphone to receive an acoustic signal from a smartphone or other portable electronic device programmed to generate a modulated, encoded acoustic vehicle entry command. Circuitry in the vehicle-mounted unit demodulates and decodes the vehicle entry command, and a transmitter in the vehicle-mounted unit transmits the demodulated and decoded command to the existing RKE receiver in the vehicle to execute the command, which may be a door LOCK or UNLOCK command. A passive RKE embodiment is also disclosed.
