Abstract: An example apparatus may perform concurrent threshold voltage compensation in a memory array with distributed row redundancy. The example apparatus may include a memory cell array having a mat having a plurality of row sections that each include respective prime memory cell rows and a respective redundant memory cell row. The example apparatus may further include a row decoder configured to receive an access command and a prime row address. The row decoder may be configured to, in response to a determination that the prime row address matches a defective prime row address, concurrently initiate a threshold voltage compensation operation on both of a prime row of the respective plurality of prime rows of memory cells of a first row section of the plurality of row sections corresponding to the prime row address and the respective redundant row of a second row section of the plurality of row sections.

Abstract: A projector includes a projection portion projecting an image on a screen by scanning a laser beam emitted from a laser beam generation portion, a light detecting portion detecting at least the laser beam reflected by a detection object, and a control portion configured to perform control of accepting an apparatus operation on the basis of a detection result of the laser beam reflected by the detection object obtained by the light detecting portion and control of detecting the breakage of the screen on the basis of a detection result of the laser beam reflected by the screen obtained by the light detecting portion.

Abstract: The invention provides a remote monitoring system which has a simplified configuration and is capable of remotely monitoring the current state of a person needing care and detecting an abnormality in the person's behavior and then addressing the abnormality, and further provides a method using the remote monitoring system.

Abstract: A client-server system in which a client terminal apparatus has communication with a server apparatus via one of a plurality of channels of a wireless LAN. When the server apparatus is in a no-connection status with the client terminal apparatus, the usage of a plurality of channels is searched. The priority levels of the use of the plurality of channels are decided based on the search result. When the server apparatus is connected to the client terminal apparatus, the usable channels in the wireless LAN are set in the order of descending priority levels.

Abstract: The invention provides a remote monitoring system which has a simplified configuration and is capable of remotely monitoring the current state of a person needing care and detecting an abnormality in the person's behavior and then addressing the abnormality, and further provides a method using the remote monitoring system.

Abstract: A surveillance camera that transmits image data to a remote surveillance apparatus has an image capturing portion, an infrared receiver for receiving infrared signals from an infrared beacon disposed in each room, a GPS receiver for receiving GPS signals from a satellite positioning system, a picture combining portion for combining current position data contained in the infrared signal or the GPS signal with pictures obtained by the image capturing portion, a transmitter for transmitting combined signal of the current position data and image data to the surveillance apparatus, a memory for storing the optimal orientation data for the surveillance camera placed in a predetermined position, and a light-emitting unit for emitting light when the surveillance camera has the optimal orientation. The surveillance camera identifies the optimal orientation when the installation position of the surveillance camera is moved between different rooms.
