摘要:
An integrated circuit device includes a double-humped protrusion protruding from a surface of an inter-device isolation region. To manufacture the integrated circuit device, a plurality of grooves are formed in the inter-device isolation region of a substrate, a recess is formed by partially removing a surface of the substrate between the plurality of grooves, at least one fin-type active area is formed in a device region by etching the substrate in the device region and the inter-device isolation region, and the double-humped protrusion is formed from the surface of the substrate in the inter-device isolation region.
摘要:
An apparatus and a method for opportunistic user scheduling of two-cell multiple user Multiple Input Multiple Output (MIMO) by a base station, the method comprising: broadcasting signals through random beams to users; and receiving Channel Quality Information (CQI) from best K user set. The CQI is calculated based on all possible combinations of transmit beamforming vectors.
摘要:
The present invention relates to a smoke and carbon monoxide alarm system including a smoke and carbon monoxide alarm device and a base unit connected to the smoke and carbon monoxide alarm device through at least one of wire connection or wireless connection. The smoke and carbon monoxide alarm device can include a control circuit configured to receive an input signal and transmit an alarm signal; a first sensor coupled to the control circuit, the first sensor being configured to generate the input signal upon detecting smoke; a second sensor coupled to the control circuit, the second sensor being configured to generate the input signal upon detecting carbon monoxide; and a camera coupled to the control circuit, the camera being configured to be activated by the control circuit when the alarm signal is transmitted to an alarm. The base unit can include a cellular transceiver configured to transmit images captured by the camera to a pre-determined remote station.
