Abstract:
An optical mouse, with shade compensation, has a light source, a sensor and a controller. The light source illuminates a sampling plane of a mouse. The sensor consists of a 2-dimensional array of sensing elements to capture an image from the sampling plane and temporarily store the image into a 2-dimensional array of pixels, each having a pixel value. The controller is connected to the sensor for adjusting the pixel values according to a predetermined table, thereby achieving a shade compensation for the sensing elements.
Abstract:
A heat sink protecting retention module is described. The heat sink protecting retention module has a main frame, protective feet, hooks, and a positioning mechanism. The protective feet are disposed under the main frame to keep screws therein before the heat sink protecting retention module is installed on the motherboard so as to avoid scratching the motherboard or damaging electric components thereon. The hooks are disposed on the main frame for clamping the heat sink and the positioning mechanism are disposed around and under the main frame for aligning the heat sink protecting retention module to a central processing unit socket.
Abstract:
An elastic computer connector is described. The elastic computer connector utilizes an elastic device to couple the elastic computer connector to a corresponding computer connector with a predetermined contact force so as to eliminate a poor contact problem. The elastic computer connector includes a protection shell, contact terminals, a wire set, and at least one elastic device. The protection shell protects the contact terminals and the contact terminals are coupled to the corresponding computer connector. The elastic device provides a spring force while the elastic computer connector is coupled to the corresponding computer connector to maintain the predetermined contact force.
Abstract:
A method of forming battery grids or plates that includes the step of applying a lead alloy coating to a continuous strip of interconnected battery grids formed from a lead alloy grid material is disclosed. The battery grids may be formed by a continuous battery grid making process such as strip expansion, strip punching, or continuous grid casting. In one version of the method, the grid wires of a continuous strip of battery grids produced by a punching process are immersed in a melt of the lead alloy coating. In another version of the method, the grid wires of a continuous strip of battery grids produced by a punching process are deformed such that the grid wires have a cross-section other than the rectangular cross-section produced by the punching process and the strip of interconnected grids is immersed in a melt of the lead alloy coating. The method increases the cycle life of a battery.
Abstract:
An electronic product (for example: an industrial computer) having an airflow-guiding device is disclosed, thereby preventing most of the airflow from being carried away by power supplies, wherein most of the air flow directed towards the power supplies will result in other electronic modules failing to have proper heat-dissipation. The present invention is to install metal partition plates on the inlets of air passages among the power supplies, fan modules and both sides of the electronic modules in the electronic product, wherein each of the meal partition plate is composed of a partition main body; folded plated respectively connected to two opposite sides of the partition main body; and buffer elements (for example: sponge pads) covering portions of the other two opposite sides of the partition main body.
Abstract:
A hot swap fan module for a server is described. The server has a fixed frame for installing the hot swap fan module. The module has at least one fan electrically connected with a power plug and having two sides. Each side of the fan has four holes. Each of two identical plastic moldings has four protuberances through the four holes for imbedding each of the plastic moldings on each side of the fan.
Abstract:
A turbine blade spar wall surrounds a coolant plenum of the blade and is cast with an intermediate thickness exceeding its final or design thickness. The outer surface of the spar wall is machined to form a plurality of incomplete holes extending to bottoms located at the final thickness dimension of the spar wall. A pre-formed sheath of porous metal is fit closely around the spar wall outer surface with coolant pores in the sheath communicating with the incomplete holes. A high pressure inert gas is introduced into the coolant plenum concurrently with application of compressive forces to the sheath as both the sheath and the spar wall are raised to a high temperature whereby the sheath is diffusion bonded to the spar wall. The inert gas pressure in the coolant plenum reinforces the spar wall against the compressive forces. The inner surface of the spar wall is then chemically machined to an etch depth dimension which brings the spar wall to its design thickness and simultaneously removes the bottoms of the incomplete holes so that the incomplete holes become complete holes between the coolant plenum and the sheath of porous metal.
