Novel hair holding devices having first and second pivotally connected body members including hair gripping portions, and methods for improving existing such hair holding devices, in which the improvement involves providing the first and second body members with at least one elastomeric member for biasing the first and second body members into a closed position and for conforming to gathered strands of a user's hair when the hair gripping portions come into contact with gathered strands of a user's hair.

Hair holding device with elastic closure operation

An engine system includes a throttle actuator module and a torque control module. The throttle actuator module controls a throttle actuator based on a desired throttle area. The torque control module determines an actuator torque. The torque control module determines a rate limited torque, a maximum torque, and a minimum torque based on the actuator torque and a predetermined rate of change. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is greater than the maximum torque. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is less than the minimum torque.

A hair holding device including hingedly connected first and second body members each including hair gripping portions adapted to be squeezed by a user whereby the hair gripping portions come into contact with gathered strands of a user's hair. The device further includes a friction-type adjustment mechanism coaxially arranged with respect to the hinge for causing the hair gripping portions to remain at a point at which the hair gripping portions are squeezed together by a user. Optionally, the device may include squeezable release handles or other release mechanism, as well as a torsion spring for biasing the hair gripping portions into either an open or a closed position.

An engine management system for a vehicle includes engine and transmission control modules that are connected to a serial vehicle data bus. A dedicated serial data bus is connected to the transmission control module and the engine control module. The engine and the transmission control modules perform processor validity and integrity checks over the dedicated data bus. In an alternate powertrain management system, engine and transmission control modules are connected to a serial vehicle data bus.

Apparatus are provided for an electronic throttle control (ETC) system having a throttle body assembly. The apparatus includes a throttle actuator, an input circuit receiving sensor signals and having first, second, and third reference voltages, a first throttle position sensor (TPS) connected to the second reference voltage, a second TPS connected to the second reference voltage, a manifold absolute pressure (MAP) sensor connected to the first reference voltage, a manifold airflow (MAF) sensor connected to the third reference voltage, and a processor connected to the input circuit and transmitting a control signal to the throttle actuator based on the sensors, reference voltages, and returns. The ETC system has improved remedial actions responsive to failures of the various sensors, reference voltages, and returns.

An engine fault diagnostic system includes a diagnostic module that generates a manifold absolute pressure (MAP) error signal and that generates a mass air flow (MAF) error signal. A security module generates an air flow fault when the MAP error signal exceeds a MAP threshold and the MAF error signal exceeds a MAF threshold.

A diagnostic apparatus is suitable for use in an automobile controller and includes a power supply terminal conducting a reference voltage, a sampling circuit and a reference voltage diagnostic circuit. The sampling circuit is coupled to the power supply terminal and has an output terminal for providing sampled values of the reference voltage. The reference voltage diagnostic circuit has an input terminal coupled to the output terminal of the sampling circuit. The reference voltage diagnostic circuit maintains a historical value of the reference voltage over a predetermined time period, compares a current sampled value of the reference voltage to the historical value, and indicates a fault in the reference voltage in response to the current sampled value being different from the historical value by more than a predetermined threshold.
