摘要:
The present invention provides a new process for making a low cost powder for the manufacture of high performance bearings. Improved powders and sintered parts (e.g., bearings) are also provided. The powders of the present invention are formed by blending iron powder with fine cuprous oxide powder and elemental tin powder. The blended powders are then thermally treated under a reducing atmosphere to form a sintered cake, which is milled to a powder.

A shoring box having frame supports coupled to lateral spreader bars. The shoring box is configured to accept exterior panels in a manner capable of providing vertical translation about an exterior surface of the shoring box. The shoring box is further configured to accept a plurality of interior panels in a manner capable of providing customizable shoring above and below utility lines, pipes, duct banks, and the like. In this regard, the shoring box is adapted to shore around one or more obstructions within an excavation, trench, or hole.

Systems and methods for wireless systems provide a mechanism for resource sharing. In an embodiment, an electronic communication is routed between mobile wireless clients without first processing the electronic communication through an external domain. In an embodiment, an e-mail message is routed between mobile wireless clients without first processing the e-mail message through an external e-mail domain identified in the e-mail message. Additional apparatus, systems, and methods are disclosed.
摘要:
Disclosed are various embodiments of methods and devices for operating a processor or host controller in a mutual capacitance sensing device. Methods and devices for sorting motion reports provided to a host controller or other processor in a mutual capacitance sensing device, reporting touch points to a host controller or other processor in a mutual capacitance sensing device, improving noise robustness and navigation performance in a mutual capacitance sensing device, determining a touch area of a user's finger on a touch panel or touchpad of a mutual capacitance sensing device, and avoiding false wakeups and minimizing power consumption in a mutual capacitance sensing device having a touch panel or touchpad are described.
摘要:
Several different methods of testing the integrity and proper operation of the drive and sense electrodes in a mutual capacitance sensing device such as a touchscreen or touchpad are disclosed herein. According to one embodiment, measured values of mutual capacitance corresponding to individual cells in a mutual capacitance sensing device are compared to one another and to predetermined thresholds. The results of the comparison are employed to determine whether any of the traces forming the electrodes in the device are defective. By way of example, traces can be defective if they are broken, too thin, too thick, or shorted together. The various embodiments of the methods disclosed herein may be used for touchscreen or touchpad quality control in a manufacturing setting, or may be used to test touchscreens or touchpads that have already been incorporated into electronic devices. The various methods disclosed herein lower manufacturing costs, increase product quality and yield, and may be carried out quickly.

摘要:
A submount for an optoelectronic device includes a substrate, a first top pad on a top surface of the substrate, a first bottom pad on a bottom surface of the substrate and a first wrap-around contact in a sidewall recess of the substrate, in which the first wrap-around contact is coupled electrically to the first top pad and to the first bottom pad. Alternatively, or in addition, the submount includes a device mounting pad on the top surface of the substrate, a wire-bond pad on the top surface of the substrate, a contact pad on the bottom surface of the substrate and a feedthrough contact which extends through the substrate and electrically couples the wire-bond pad to the contact pad.
