摘要:
An apparatus, and a method performed by the apparatus, are disclosed wherein the apparatus can be mounted on an unmanned vehicle and arranged to act upon a payload. The payload can be mounted on the unmanned vehicle and, under an action of the apparatus, is able to be activated. The method can include receiving an activation instruction from an entity remote from the unmanned vehicle; determining whether or not the received activation instruction is valid by performing a validation process; and in response to determining that the received activation instruction is valid, activating the payload. In response to determining that the received activation instruction is not valid, activation of the payload may be prevented or opposed.

Redundancy in engine timing position sensing maintains a UAV operational in the event of failure of a primary engine timing position sub-system. The redundancy avoids duplication of the primary crankshaft timing position sensing components, and avoids adding weight, cost and component complexity. Conditioned (square) waveform(s) (102) is/are created from respective sinusoidal waveform(s). Each consecutive leading edge (103a) and trailing edge (103b) of the pulses of the square waveform (102) is derived from the crossing of the zero voltage value by consecutive sinusoidal waveforms A,B,C (e.g. Voltage (V) vs Time (t) or angular degrees). The square pulse waveform (102) is output (104) to a microcontroller (106) to create and output a pseudo crankshaft timing position signal (108) to be used by an ECU to determine ignition and fuel injection events in the event that the primary timing signal from the crankshaft position sensor (CPS) has failed. The signal (108) output to the ECU can have a missing pulse (116) (i.e. indicative of a TDC position of the engine crankshaft) as well as multiple square pulses (114) corresponding to the pulses of the initial square pulse waveform (102). The waveform signal (108) is therefore derived from the alternator waveform signal(s) and provides a pseudo crankshaft timing position signal in the event of failure of the primary or initial CPS signal.

Disclosed is a method and apparatus for determining a route for a vehicle (2). The method comprises generating, by a processor (12), a grid (16) by specifying a start node (18), specifying one or more movement operations performable by the vehicle (2), and iteratively adding edges and further nodes (20-24) to the grid (16), each edge corresponding to a respective movement operation and each further node corresponding to a location for the vehicle (2). The one or more processors (12) then select a path through the grid (16) from a first node of the grid to a second node of the grid. The first node corresponds to a first location (A) for the vehicle (2) and the second node corresponds to a second location (B) for the vehicle (2). Thus, a route for the vehicle (2) from the first location (A) to the second location (B) is determined.

An airship may include a hull (22) substantially shaped as an oblate spheroid, one or more frame members (122, 124) defining a support structure (20), wherein the support structure forms at least a partial support for the hull, at least one horizontal stabilizing member (315) operably coupled to a lower surface of the airship and at least one horizontal stabilizing member (315) having a first end and a second end. The at least one horizontal stabilizing member (315) may define an anhedral configuration. The airship may also include a vertical stabilizing member (310) having a first end pivotally coupled to the airship and a second end oriented to remain below an upper surface of the airship. The vertical stabilizing member (310) may be configured to pivot within a vertical plane and the first end of the vertical stabilizing member and the first end of the at least one horizontal stabilizing member may be operably coupled to one another.
摘要:
Systems, methods, and devices of managing a battery assembly used to power an object are provided to discharge a battery assembly for a safe and long-term storage. A controlled self-discharge of the battery assembly may be initiated when the power to the object is turned off for a certain length of time or the battery assembly is not in use for a threshold length of time. The controlled self-discharge may be terminated if the battery assembly reaches a threshold voltage value or the battery is in use again during the self-discharge.

An unmanned aerial vehicle apparatus comprises a frame. Further, the unmanned aerial vehicle apparatus comprises a propulsion mechanism coupled to the frame that propels the frame through the air. In addition, the unmanned aerial vehicle apparatus comprises a storage device that stores one or more airbags and is coupled to the frame. The unmanned aerial vehicle apparatus also comprises an inflation device coupled to the frame that receives an activation signal and inflates the one or more airbags based upon receipt of the activation signal to deploy the one or more airbags from the storage device prior to an impact of the frame with an object.
