    摘要: An automatic door opener for delivery trucks may include a door opener motor, clutch, and transmission which are connected to a door opener rail. The automatic door opener is attached to the roof of a delivery truck cargo bay and the door opener motor is operable to open and close a cargo door. The clutch and motor are controlled by a motor control computer which may be programmed to automatically operate the clutch, close the cargo bay door, and disengage the clutch as desired. A rail carriage may be connected to the cargo bay door by a door connector arm which includes a quick release connection to the carriage and which may be operated from the outside of the cargo bay door. A sensor may be connected to the door opener rail and to the motor control computer such that the motor control computer tracks the position of the carriage along the door opener rail independent of the operation of the motor.

    摘要: In one embodiment, a method is provided for measuring a dynamic phase offset between a PLL's input clock and the PLL's feedback input clock, wherein the input clock is spread spectrum modulated in a spread spectrum mode and is not modulated in a static mode. The method includes: in the spread spectrum mode, measuring phase jitter between the input clock and the feedback input clock to form a spread spectrum phase jitter measurement; in the static mode, measuring phase jitter between the input clock and the feedback input clock to form a static phase jitter measurement; and comparing the spread spectrum phase jitter measurement to the static phase jitter measurement to determine the dynamic phase offset.

    摘要: To enable a tractor bonnet to be opened and closed it is pivotably connected near its front end to longer arms of respective laterally-spaced interconnected bell-crank levers which are pivotably mounted about a common transverse axis on an upstanding sub-frame secured to the tractor's main frame. When the bonnet has been initially moved forwardly, thus pivoting the levers relative to both the bonnet and the sub-frame, the shorter arms of the levers abut against the sub-frame whereafter the rear end of the bonnet is secondarily moved upwardly and forwardly into opened position by pivoting the bonnet relative to the stationary levers. The bonnet is closed by performing the same movements in reverse sequence, a transverse arch preferably being so fixed relative to the main frame as to guide the bonnet near the end of its initial closing movement.
