Description
Electronic Shelf Label, also known by the acronym ESL. It is the latest solution for inventory and price management in the retail sector, based on the use of advanced IT technology. ESL replaces conventional paper price tags attached to the shelves of supermarkets and department stores with, for example, LCDs and electronic paper (E-paper) that show information on product price, sales promotions, etc.
ESL takes advantage of Zigbee, a low-power wireless communication technology, to keep product prices updated in real time. ESL consists of an e-paper equipped tag and gateway which delivers product information. The central server transmits information of each product to the gateway, which in turn sends such information to thousands of tags at the same time.
An electronic shelf label includes a transceiver configured to communicate with a plurality of wireless data tags associated with a plurality of retail products.

Description
A digital isolator is used to get a digital signal across a galvanic isolation boundary. They serve a similar purpose to optocouplers, except optocouplers are far too slow and error prone for high speed (1MHz+) digital signals. They also use a different coupling technology, usually transformer or RF link as opposed to an optical link.
While digital isolators only work with digital signals, they are frequently used to transfer digitised versions of analogue signals. The resulting signal chain will have better bandwidth, accuracy and linearity in comparison to an optocoupler based system. Optocouplers have inherent non-linearity and high unit to unit variations (+- 50% of your signal), so the circuit will need to immune to these variations or each unit individually calibrated.
Multiplexing digital channels across a single digital isolator path can be achieved very easily, which in turn simplifies the circuit and results in a net cost saving in-spite of using a more expensive isolation technology. In short, digital isolators are a superior to optocouplers in almost every regard.
Description
Diffractive optical elements, DOEs, were designed for applications with lasers and high-power lasers. Used as multi-spot beam splitters, in beam shaping, and beam profile modification, such elements offer endless possibilities in different application fields.
Diffractive optical element uses a thin micro structure pattern to alter the phase of the light propagated through it. When a laser beam is transmitted through a diffractive optical element (DOE), it can be transformed into an almost arbitrary light pattern in the observation plane.
Description
This report studies the Low Density SLC NAND Flash Memory market. SLC (Single Level Cell) NAND is the original NAND architecture. Its much higher endurance (vs.MLC) makes it ideally suited for a variety of consumer and industrial applications where longevity of supply is important. Low-density SLC refers to (<16-Gbit) SLC NAND flash memory.
Description
Landline Phones are a kind of phone that uses a metal wire or optical fiber telephone line for transmission as distinguished from a mobile cellular line, which uses radio waves for transmission.
Description
An image sensor or imaging sensor is a sensor that detects and conveys the information that constitutes an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation. Image sensors are used in electronic imaging devices of both analog and digital types, which include digital cameras, camera modules, medical imaging equipment, night vision equipment such as thermal imaging devices, radar, sonar, and others. As technology changes, digital imaging tends to replace analog imaging.
