An optical recording medium structure and its method of manufacture. The optical recording medium structure includes, from bottom to top, a transparent substrate, a first dielectric layer, a first buffer layer, a recording layer, a second buffer layer, a second dielectric layer, an optical compensation layer and a reflection layer. The optical recording medium structure is manufactured by forming the first dielectric layer, the first buffer layer, the recording layer, the second buffer layer, the second dielectric layer, the optical compensation layer and the reflection layer in sequence over the transparent substrate. The first buffer layer and the second buffer layer serves to prevent the diffusion of at least one element from the recording layer into the first and the second dielectric layer and vice versa. The optical compensation layer enhances thermal sensitivity of the recording layer during an optical read/write operation.

Methods, apparatus and systems for enhanced wireless monitoring of vital signs are described. In one example, a described system comprises: a transmitter configured to transmit a wireless signal through a wireless channel of a venue; a receiver configured to receive the wireless signal through the wireless channel; and a processor. The received wireless signal differs from the transmitted wireless signal due to the wireless channel that is impacted by a periodic motion of a vital sign of an object in the venue. The processor is configured for: obtaining a time series of channel information (CI) of the wireless channel based on the received wireless signal, computing a two dimensional (2D) decomposition of the time series of CI (TSCI), enhancing the 2D decomposition, and monitoring the periodic motion of the vital sign based on the enhanced 2D decomposition.

摘要:
A variable-tooth-thickness worm-type tool comprises a main body and a spiral blade distributed on the main body and featuring variable tooth thickness. The main body and the spiral blade are respectively described with a rack cutter coordinate system and a tool coordinate system. The vector parameters based on the rack cutter coordinate system are transformed into vector parameters based on the tool coordinate system so as to simulate the main body with a rack cutter and develop the spiral blade to have variable tooth thickness. Thus, when a gear blank is tooled, the distance between the centers of the tool holder and the workpiece holder can be set as a constant, and the feed in the radial degree-of-freedom can be neglected, with twists of tooth flanks being inhibited.

The present invention discloses an integrated system for remote monitoring home appliances by a cell phone. In the integrated system, a cell phone sends an instruction message to a computer by a wireless network. A digital control disk connected with the computer generates a control signal in accordance with the instruction message. The control signal is sent by a wireless transceiver circuit to a home appliance. Moreover, a state signal that includes information of the home appliance operation can be sent to the digital control disk. Through the computer connecting to the wireless network, the cell phone is informed of the information of the home appliance operation. Thereby, the user can control the home appliances and acquire the current operation states of the home appliances by his/her cell phone.
