An emergency lubrication system for a turbine engine includes a reservoir 50 containing a reserve quantity of lubricant 52 and having a lubricant inlet 54 and a lubricant outlet 56. A lubricant supply line 62 and a lubricant outlet line 66 each have a respective valves 64, 68 for regulating lubricant flow into and out of the reservoir. A fluid supply line 70 includes a valve 72 for selectively establishing communication between the reserve quantity of lubricant and a source of pressurized fluid. During normal operation the lubricant outlet valve continuously releases lubricant at a normal rate to the component requiring lubrication while the lubricant inlet valve concurrently admits fresh lubricant into the reservoir. During abnormal operation, the lubricant inlet valve closes in response to abnormally low lubricant pressure outside the reservoir thereby preventing backflow of reserve lubricant out of the reservoir. The fluid inlet valve opens to admit pressurized fluid into the reservoir thus pressurizing the reserve lubricant. The lubricant outlet valve opens or cycles open and closed in response to a command from a controller 26 so that the pressurized fluid forces lubricant through the outlet 56 as a subnormal rate, which persists until the lubricant reserve is substantially depleted. The subnormal rate is ideally achieved by intermittently releasing lubricant from the reservoir, but may also be achieved by releasing a continuous stream of lubricant at a rate less than the normal rate of release.

The invention relates to an access unit (5; 23) for communicating with a further access unit (5; 23) to control access to a vehicle (3). The access unit (5; 23) comprises at least a first transmitter (11; 25) for transmitting a polling signal; and at least a first receiver (11; 25) for receiving an authentication signal from the further access unit (5; 23) in response to the polling signal. At least the first transmitter (11; 25) is a first ultra-wideband transmitter and at least the first receiver (11; 25) is a first ultra-wide-band receiver. The invention also relates to a vehicle access system (1) which is a combination of the access and further access units (5; 23). The invention also relates to methods of operating a vehicle access system (1) and a vehicle access unit (5; 23).

An electronic device with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface: detects, on the touch-sensitive surface, a gesture that includes an increase of intensity of a contact above a respective intensity threshold. In response to detecting the gesture: in accordance with a determination that the gesture includes a first number of contacts, the device generates a tactile output on the touch-sensitive surface; and in accordance with a determination that the gesture includes a second number of contacts different from the first number, the device forgoes generating the tactile output on the touch-sensitive surface.

A transcutaneous charging device for charging an implant comprising:a power input;a conversion circuit to convert power from said power input to transcutaneously charge said implant;a control; andan indication element;wherein said control is programmed to initiate an indication using said indication element when it is time to charge said implant.

Described is a mechanism for mobile devices that allows a user to set a time at which the mobile device will automatically power down, and another time at which the mobile device will wake up. The mechanism further allows the mobile device to be awakened earlier than the wake up time if an event is scheduled to occur prior to the wake up time. Furthermore, the mechanism provides for the cancellation of the automatic power down or wake up, based on user input.
