Abstract: A method for attaching processors and other components to printed circuit assemblies. One particularly useful application for several embodiments of the invention is attaching a single-edge-contact processor to a PCB. In one embodiment, a mounting-module for attaching a component to a PCB is attached to the PCB prior to being shipped to a final device manufacturer. The component has a component height greater than a desired shipping height for the printed circuit board. The mounting-module, more particularly, may have a base attached to the printed circuit board and a component holder attachable to the base. The base and component holder together may have a first height less than the desired shipping height when the component holder is in a detached or lowered position. As such, the base may be attached to the printed circuit board prior to shipping without adversely impacting the shipping costs.

Abstract: One embodiment of the present invention provides a method for skipping a track on a disc in a disc player. Unlike current methods, this method does not rely on identifying tracks to be skipped based upon which slot a disc is located in. Instead, one embodiment of the present invention identifies discs based upon identification data read from discs in the disc player. Thus, this embodiment of the present invention provides a method for skipping a track on a disc in a disc player that operates by identifying discs contained in the disc player. The method receives track identification data from a track sequencer. The method also reads track identification data for tracks to be skipped from a memory storage device. The method then compares the track identification data for the tracks to be skipped with the track identification data from the track sequencer.

Abstract: A closure system useful for securing a device having a stylus. In a first embodiment, the closure system includes a housing having first and second housing members, the first housing member being configured to matingly contact the second housing member when the device is in a closed configuration. The stylus is received within a channel located in the second housing member. A latch release also located within the second member is controlled by the position of the stylus such that when the stylus is inserted within the channel, the latch release engages a latch located on the first member, thereby preventing the first and second members from separating. The latch release may also be used to block the latch such that the first and second housing members can not be mated when the stylus is removed from the channel. In another embodiment, a blocking device located within the second housing member and separate from the latch is utilized to prevent the device from being closed when the stylus is removed.

Abstract: The present invention provides a method for identifying components based upon selected physical characteristics. Initially, a characterization function that will produce a unique characterization value within a set of components, is (or has been) assigned to the set of components. The characterization function is a function of at least one physical characteristic that is shared by the components within the set of components. Next, the measurable physical characteristics defined as part of the characterization function are measured by testing. A characterization value, which is calculated from the assigned characterization function, is determined for each component. Each component that is to be subsequently identified is then identified by its associated characterization value.
