Abstract: A package module for an image sensing device is provided. The package module includes a substrate having thereon a photoelectric element array, a first optical element array formed on the photoelectric element array, a package lid having thereon a second optical element array opposite to the first optical element array and having an arrangement corresponding to that of the first optical element array; and a spacer disposed on a bonding area between the package lid and the substrate for adjusting a distance between the package lid and the substrate.

Abstract: An optoelectronic device chip, and a method for making the chip, are disclosed. The chip comprises a device substrate, an optically transparent upper substrate, and a composite spacer layer which includes an adhesive material and a plurality of particles dispersed in said adhesive material. The distance between the device substrate and the upper substrate is controlled by the thickness of the composite spacer layer so that the variation is within the depth of focus of optical system.

Abstract: An image sensor module comprises an image sensor chip, at least one lens layer, and at least one bonding layer. The image sensor chip has an image capturing zone manufactured with an image capturing element, and a partition zone surrounding the image capturing zone. The at least one lens layer is stacked on the image sensor chip, having a transparent substrate and a lens mounted on the transparent substrate and adapted to focus the projected image onto the image capturing zone of the image sensor chip. The at least one bonding layer is arranged corresponding to the partition zone of the image sensor chip and bonded between the image sensor chip and the at least one lens layer, mixing of a glue agent and a plurality of spacer elements with which the height of each the spacer elements is determined to be the height of the bonding layer.

Abstract: A roller retainer for the third axis of a mouse comprises a seat, an upper cover and a roller seat. The seat has a housing, a circuit board and other components. The circuit board is installed with a microswitch and an IR module seat. A via hole is formed at the middle portion of the roller seat. The via hole serves to place a roller seat therein. A rear end of the roller seat is buckled to the rear inner end of the upper cover, and the roller seat may be like a suspending arm. The roller seat has a function of plastic resilient and therefore, no elastic spring is necessary. The roller seat is installed with an upper cover and other components is still installed in the seat. Therefore, no space in the circuit board is occupied and thus cost is reduced and material can be prepared easily.

Abstract: A computer keyboard with Z-axis input means is characterized in that at least one scrolling means compatible with that of a mouse, a cursor moving means and at least one mouse button are integrated on a keyboard with or without multimedia hotkeys. The novel keyboard consists of a traditional key matrix, a control unit, and a mouse equivalent unit. The mouse equivalent unit further consists of scrolling means, pointing means, and mouse button means, all of which are electricaly connected to the control unit. Through the all-in-one keyboard, user not only can perform typing task, operate mouse functions, but also scroll windows client area up and down, and left and right if a second scrolling means is provided.
