摘要： A voltage controlled oscillator (VCO) comprising a first supply node, a second supply node, an oscillation transistor, a biasing network, an output node and a feedback network is described. The VCO is be powered by a supply voltage applied across the first and second supply nodes. The oscillation transistor and the biasing network are connected in series between the first supply node and the second supply node. The output node is connected to the oscillation transistor so as to deliver an oscillatory output signal. The feedback network provides an oscillatory feedback signal from the output node to the biasing network. The feedback network comprises a capacitive element and a transmission line connected in series for transferring the feedback signal. The VCO may be integrated in a radar device, for example.

摘要： Systems and methods are provided for authenticating an input on a touch screen. A method comprises obtaining one or more pressure metrics for an input by a user on a touch screen that is being proffered as that of a known user. Each pressure metric corresponds to a pressure applied to the touch screen by the user at a respective impression location of the input. The method further comprises authenticating the user as the known user based at least in part on the one or more pressure metrics.

摘要： A touch-screen display apparatus, the apparatus may include first and second sheets having opposed major surfaces and a size and shape defined by a periphery. The periphery may be defined by opposed ends and opposed edges. The first and second sheets may each have a conductive pattern including a pair of opposed busbars and a plurality of traces electrically coupled to, and extending between, corresponding pairs of opposed busbars. The transparent force sensing (TFS) sheet may have opposed major surfaces and a variable resistance which is related to a force exerted upon one or more of its major surfaces. The TFS sheet may be situated between the first and second sheets. The apparatus may also include one or more separation portions situated between the TFS sheet and the first or second sheet to bias the TFS sheet apart from the first or second sheet.
