Abstract: An electronic circuit including a plurality of common terminals, a first circuit, a second circuit, and a plurality of switch units is provided. The first circuit is configured to output display driving signals to data lines of a display panel via the common terminals. The second circuit is configured to receive fingerprint sensing signals from fingerprint sensing lines of the display panel via the common terminals. Each of the switch units includes a first terminal coupled to one of the common terminals and a plurality of second terminals coupled to the first circuit and the second circuit. The switch units are grouped into a plurality of groups, and each group corresponds to a fingerprint sensing channel of the second circuit.

Abstract: An electronic circuit for operating with a display panel including touch sensors and fingerprint sensors is provided. The electronic circuit includes a first circuit, a second circuit, a third circuit, a first switch circuit and a control circuit. The first circuit generates display driving signals for driving the display panel. The second circuit receives fingerprint sensing signals from the fingerprint sensors. The third circuit determines a touch information according to touch sensing signals from the touch sensors. The first switch circuit includes a plurality of first switch units, each of the first switch units includes a first switch element and a second switch element. The control circuit controls the first switch circuit to transmit the display driving signals in a first time interval, controls the first switch circuit to transmit the fingerprint sensing signals in a second time interval, and controls the third circuit to receive the fingerprint sensing signals in a third time interval.

Abstract: A pump includes a cylindrical main body comprising a central channel, four valve assemblies each threadedly fastened in a radial hole, first and second cavities disposed to each hole and communicating therewith, a spring activated first check valve in each first cavity, a spring activated second check valve in each second cavity, an outlet, a threaded outlet orifice communicating with the outlet, an inlet, a threaded inlet orifice communicating with the inlet, four plungers each in a plunger chamber communicating between the hole and the channel, opposite outlet and inlet tunnels, two snapping members each having a central hole and a snapping bifurcation at either bent end, the snapping bifurcation slidably put on an end of the plunger; a top cover; a bottom cover; and an eccentric shaft having one end secured to motor shaft and other portions in the main body to operatively secure to the snapping members.
