Abstract: A constant-current circuit apparatus for a parallel LED luminaire is disclosed. The circuit apparatus includes an electrical connector unit and one or more parallel-connected constant-current LED light module unit. The electrical connector unit includes an input unit and an output unit connected in parallel. The current from the power source flow through the input unit of the first parallel LED luminaire to its constant-current LED light modules and through its output unit to the next parallel LED luminaire connected to it. A constant-current LED light module unit includes an LED light module unit and a current regulation unit. The current regulation unit regulates the current at a constant value flow through the LED light module unit. The LED light module unit includes one or more LED cluster unit connected in series. Each LED cluster unit includes more than one LED component and a bypass diode connected in parallel.

Abstract: A computer includes a touch element, a projection module, and a calculating element. The touch element has an operating area. When the operating area is touched, the touch element generates an input signal. The projection module is used for projecting an operating image in the operating area. The calculating element is connected with the projection module and the touch element and is used for processing the input signal to transform the input signal to a touch signal.

Abstract: An adjustable finger ring includes an ornament member and a pair of shank members held by the ornament member. The ornament member includes an E-shaped setting section and a clipping section pivotally connected with the setting section. The setting section has two side-by-side grooves disposed at a bottom side thereof. Each of the grooves is provided with a projected pin. The shank member is substantially C-shaped and provided with a flat top section and a curved bottom section. A width and a thickness of the top section are corresponding to the groove. The top section includes a plurality of adjustment holes disposed along a longitudinal direction thereof. The shank members are received in the grooves and held by the setting section and the clipping section. The size of the ring is adjusted by inserting the projected pin into one of the adjustment holes.
