    摘要: A method for executing mechanical overload protection to prevent commanding a control signal to a linear actuator that may mechanically overload the linear actuator when an overload condition of the linear actuator is detected, the linear actuator utilized for controlling a movable element associated with the linear actuator responsive to the control signal, includes monitoring an overload condition based on position change of the movable element associated with the linear actuator during an integration period and excess energy during the integration period, de-energizing the linear actuator when an overload condition has been detected, monitoring an overload retry counter based on the number of cycles the overload condition is detected, comparing the overload retry counter to an overload retry threshold, an reenergizing the linear actuator when the overload retry counter is less than the overload retry threshold and maintaining de-energizing of the linear actuator when the overload retry counter is at least the overload retry threshold.

    摘要: An energy harvesting system comprises a first region having a first temperature and a second region having a second temperature. A heat engine is configured for converting thermal energy to mechanical energy. The heat engine includes a plurality of discrete elements of a shape memory alloy each having a crystallographic phase changeable between austenite and martensite in response to a temperature difference between the first region and the second region. At least one member of the heat engine is driven to rotate about a first axis by the phase change of the plurality of discrete elements.

    摘要: A method for detecting a mechanical overload condition of an energized linear actuator to prevent commanding an activation signal to the linear actuator that may mechanically overload the linear actuator includes monitoring feedback variation of a movable element associated with the linear actuator including monitoring a present feedback signal of the movable element, monitoring a previous feedback signal of the movable element, comparing the present feedback signal and the previous feedback signal and determining the feedback variation based on the comparing. The feedback variation is compared to a feedback variation threshold. An input signal associated with the activation signal for controlling the linear actuator is monitored and the input signal compared to an input signal threshold. The electrical overload condition is detected when the feedback variation is less than the feedback variation threshold and the input signal is greater than the input signal threshold.

    摘要: A pumping assembly is provided. The assembly includes a first movable element selectively movable within a first pump housing and an actuator including an active material. The active material is configured to undergo a change in attribute in response to an activation signal. The active material is operatively connected to the first movable element such that the change in attribute causes the first movable element to move within the first pump housing. In one example, the active material is a shape memory alloy material having a crystallographic phase that is changeable between Austenite and Martensite in response to the activation signal.

    摘要: A vehicle is provided having a sensor for detecting a vehicle occupant's presence, and another sensor for detecting an owner's response with respect to automatically opening a vehicle closure panel. An actuator opens the closure panel when the occupant's presence and response are detected. A signal from an emitter outside the vehicle signals occupant presence. A photoelectric and/or optical device, audio receiver, and/or touch-sensitive sensor detects the response. The optical device projects a light beam, and breaking the beam with a gesture signals the response. An automatic closure panel opening apparatus has an RF receiver adapted to receive an RF signal to detect occupant presence, a sensor for detecting the occupant response, and an actuator for opening the closure panel when both the presence and occupant response are detected. A method for automatically opening the closure panel includes detecting an occupant presence and response, and automatically opening the closure panel when a predetermined response is detected.
