Abstract: The present invention provides a method for wireless backhaul frequency band flexible allocation. It is able to use the uplink band of FDD band as the wireless backhaul uplink and downlink band of small cells. When the status is having a plurality of FDD bands and a heterogeneous network with big cells and one or more small cells, the present invention is able to efficiently use uplink band of the FDD band as the wireless backhaul band of the one or more small cells.

Abstract: A method of providing Global Positioning System (GPS) signals received by a cradle to a portable electronic device installed in the cradle includes mounting the portable electronic device in the cradle for establishing electrical connection between a first connector of the cradle and a second connector of the portable electronic device, receiving GPS signals through a GPS receiver of the cradle, converting the received GPS signals into GPS data signals, transmitting the GPS data signals from the cradle to the portable electronic device via the first and second connectors, and the portable electronic device using the GPS data signals for aiding the portable electronic device in determining current position coordinates of the portable electronic device.

Abstract: A method for earthquake-proof mounting a semiconductor process machine on a removable floor (or a raised floor) in a semiconductor fabrication plant. In the method, a modified I-beam which has a horizontally extending upper flange is provided for mounting under a removable floor and attaching through the floor directly to a process machine situated on top of the floor. The process machine may be attached to the modified I-beam through an L-shaped bracket that is attached to the support frame of the process machine with the horizontal flange of the bracket attached to the modified I-beam through apertures in the removable floor. The present invention further comprises an earthquake-proof mounting fixture for mounting a process machine on a removable floor in a semiconductor fabrication plant.
