Abstract:
An antenna for radiating an electromagnetic field includes a ground plane, a first dielectric layer disposed on the ground plane, and a second dielectric layer disposed on the first dielectric layer. The antenna includes at least one feeding element embedded in the first dielectric layer and a radiating element extending from the feeding element. The radiating element is embedded within the first dielectric layer adjacent to the second dielectric layer. A beam steering element is embedded in the second dielectric layer and electromagnetically coupled to the radiating element. Embedding the beam steering element in the second dielectric layer and electromagnetically coupling the beam steering element to the radiating element allows the antenna to tilt a radiation beam to overcome a roof obstruction from a vehicle while maintaining acceptable gain, polarization, and directional properties for SDARS applications.

Abstract:
A pointing device mounted in a portable computer having a system unit for data processing, wherein the pointing device comprises a housing detachably attached to the portable computer, and a first and second input means formed integrally with the housing, wherein the first input means is used for data input by making wireless data communication with the system unit when the housing is detached from the portable computer, and the second input means is directly connected with the system unit through a cable for data input when the housing is attached directly to the portable computer. Preferably, the housing may be detachably mounted in a seat provided in the system unit of the portable computer. The first and second input means are respectively a ball type mouse and a touch pad. Thus, the pointing device may be selectively used as a ball type mouse when detached from the system unit or as a touch pad when attached to the system unit. Used as the ball type mouse, the pointing device transfers the pointing data to the system unit by means of a radio transmitter. Used as the touch pad, the pointing device transfers the pointing data to the system unit by means of cable connection.
Abstract:
A computer system having two fixed disk drives and with a different operating system stored in each disk drive, in which selective booting and suspend/resume operation of the power management can be preformed through the two fixed disk drives. The computer system comprises a first hard disk drive storing a first operating system and a second hard disk drive storing a second operating system, each of the first and second hard disk drive has a reserved data storage area for the suspend operation. A port exchanger intervenes in the master and slave integrated drive electronics (IDE) interface signal lines leading from an integrated drive electronics (IDE) controller to the first and second hard disk drives, in response to a bus exchange control signal fed from a system controller to pass or cross switch the integrated drive electronics (IDE) interface signal paths directed to the first and second hard disk drives. The computer system further includes a controller for producing the bus exchange control signal, under control of the system management part by referring to the first and second hard disk drive status information during booting or resuming process.
Abstract:
An apparatus for assembling a door and a main body in a microwave oven is disclosed, in which a door can easily be mounted in a main body of a microwave oven. The apparatus for assembling a door and a main body in a microwave oven includes a hinge plate mounted in a main body of a microwave oven, a hinge shaft mounted in a cut-open portion of a choke cover fixed to a door, for being rotatably fixed to the hinge plate, and a detachment prevention portion elastically deformed to allow the hinge plate to be fixed to the hinge shaft and restored to the original state if the hinge plate is completed to be fixed to the hinge shaft to prevent the hinge plate from being detached from the hinge shaft. The detachment prevention portion includes a supporting portion for supporting the hinge plate when the hinge plate is fixed to the hinge shaft, and a vertical portion connected to one end of the supporting portion.
Abstract:
A window assembly for a vehicle has a transparent layer including a metal compound such that the transparent layer as is electrically conductive. The transparent layer defines an area covering the window assembly. An outer region which is electrically non-conductive surrounds the area. The window assembly includes an antenna element including wire or transparent coating disposed within and surrounded by the outer region without extending into the transparent layer. The antenna element is electrically disconnected from the transparent layer such that the antenna element operates independent of the transparent layer. A feeding element is coupled to the antenna element for energizing the antenna element. The feeding element is electrically disconnected from the transparent layer such that the feeding element energizes the antenna element independent of the transparent layer.

The present disclosure relates to computer-implemented systems and methods for establishing a wireless display connection. A user device may detect, by an RFID tag, a signal from a wireless display device. As a result, the user device may transmit, by the RFID tag to the wireless display device, radio communication information. To this end, the user device and the wireless display device may establish a radio connection. Using the radio connection, the user device may receive wireless display connection information from the wireless display device. The user device may establish, using wireless display connection information, a streaming wireless display connection with the wireless display device.

The method may also include establishing, by the radio transceiver based at least in part on the verification, a radio connection with the base station.
Abstract:
Disclosed herein are a soldering connecting pin, a semiconductor package substrate and a method of mounting a semiconductor chip using the same. A semiconductor chip is mounted on the printed circuit board using the soldering connecting pin inserted into a through-hole of the printed circuit board, thereby preventing deformation of the semiconductor package substrate and fatigue failure due to external shocks.
