  • Patent number: 11615257
    Abstract: Disclosed is a reader device, system, and method for communicating with a wireless sensor. The reader device may be configured to communicate wirelessly with an implant device associated with a proprietary system provided by a first entity. An external device, that may not be associated with said first entity, is provided and is configured to be calibrated to communicate with the implant device that is located within a patient. The external device may be used in place of an existing reader device that was initially calibrated to communicate with the implant device prior to the implant device being placed within the patient. The external device may be particularly useful for implant devices that communicate wirelessly with external devices where said implant devices are intended to be located within the human body on a permanent or indefinite duration of time.

  • Publication number: 20230072070
    Abstract: Disclosed are a reader device, system, and method for communicating with a wireless sensor. The reader device may be configured to analyze the strength of a response signal transmitted from the wireless sensor in response to an excitation pulse generated by the reader device. In one embodiment, the reader device may be configured to engage be placed in a plurality of modes to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the wireless sensor to output a resonant signal. The reader device may receive the resonant signal from the wireless sensor and evaluate it against predetermined values. The evaluated signals may be used to assess the strength and the proximity of the reader device relative to the wireless sensor as it is implanted in a patient.

  • Patent number: 10801430
    Abstract: Air to fuel ratio management comprises sensing a power output request for the engine and determining a fuel-efficient air to fuel ratio. A current air to fuel ratio is sensed in one or both of an intake manifold and an exhaust manifold connected to the engine. An air to fuel ratio adjustment is determined based on the fuel-efficient air to fuel ratio and based on the current air to fuel ratio. An in-cylinder exhaust gas recirculation technique is selected. The in-cylinder exhaust gas recirculation technique adjusts an oxygen and particulate content of exhaust gas resulting from combustion. A number of cylinders of the multiple-cylinder engine are selected to implement the in-cylinder exhaust gas recirculation technique. The intake valves and the exhaust valves are controlled to adjust the oxygen and particulate content of the exhaust gas by applying a second compression stroke of the respective reciprocating pistons to the exhaust gas.

  • Patent number: 10774694
    Abstract: A valve train assembly includes an intake rocker arm, an exhaust rocker arm, a carrier configured to couple to a cylinder block and operably associated with the intake rocker arm and the exhaust rocker arm, the carrier including a first aperture, and a cylinder deactivation (CDA) capsule disposed within the first aperture. The CDA capsule is configured to move between a latched condition that transfers motion from a push rod to one of the intake rocker arm and the exhaust rocker arm, and an unlatched condition that absorbs motion from the push rod and does not transfer the motion to the intake rocker arm or the exhaust rocker arm.

  • Patent number: 8036211
    Abstract: A Legacy User Proxy CSCF (“L-CSCF”) provides multimedia services from a SIP based network to legacy access networks and devices. The L-CSCF includes a legacy service control state machine; a P-CSCF state machine and associated protocols; a mapping between a user's legacy network address and a corresponding network entry point; a database and logic for mapping between legacy user addresses and corresponding authentication data; legacy specific QoS control mechanisms; and an interworking function to handle incompatibilities between the legacy and SIP call models. The L-CSCF may be disposed logically between the legacy network and the multimedia network to translate and process communications such that legacy network and multimedia network devices need not require extensive modifications in order to support operation.
