摘要： A method of micro-machining a semiconductor substrate to form one or more through slots therein. The semiconductor substrate has a device side and a fluid side opposite the device side. The method includes diffusing a p-type doping material into the device side of the semiconductor substrate in one or more through slot locations to be etched through a thickness of the substrate. The semiconductor substrate is then etched with a dry etch process from the device side of the substrate to the fluid side of the substrate so that one or more through slots having a reentrant profile are formed in the substrate.

摘要： A method and apparatus are provided for allocating resources in a communication network including at least one access point exchanging data with at least one terminal connected thereto, and managing at least two communication channels. The method in the access point implements a phase of associating and authenticating a terminal with the access point, including a step of associating a unique identifier with the terminal, and a phase of managing the assembly of channels. The phase of managing includes implementing a reference table associating one of the channels to a terminal identified by the unique identifier thereof, including the following steps: detecting a switching of a terminal connected with the access point, from an initial channel to a destination channel; and updating the reference table to associate the unique identifier of the terminal to the destination channel.

摘要： A method and device are provided for transmitting data packets to an access network with sharing of a multiband channel among stations. A first band is referred to as a “transmission” band, and a second band is referred to as a “signaling” band. A station accesses the channel for transmitting data of a stream after using a counter to decrement a backoff value. The method includes: receiving backoff counts sent successively over the signaling channel by the various stations relating to their various streams; comparing the backoff counts with one another in order to detect identical values; and in the event of there being identical values between a plurality of stations, determining at least one new backoff count value that is different from all the others.

摘要： The invention relates to a system and method of dispersion measurement in an optical fiber network. The invention provides means for transmitting from a transmitting node, using a single tunable laser transmitter, two consecutive bursts of data at different wavelengths λ1 and λ2 to a receiver node, wherein each burst of data comprises a unique sequence of amplitude modulated data, and wherein the two sequences are injected with a fixed known delay. The delay between the two consecutive bursts of data is maintained by selective switching of the tunable laser, such that clock recovery circuitry at the receiver node remains locked during the delay between the two bursts. The dispersion measurements method of the present invention is based on walk off and bit position detection between two wavelengths suitable for fast optical burst switching network is described. This method does not require an operator, extra equipment, or traffic interruption on the network.

摘要： A technique that minimizes false triggering of an electrostatic discharge (ESD) protection circuit is disclosed. In an embodiment, the resistor-capacitor (RC) time constant of an ESD trigger element is reduced during normal operation minimizing the risk of false triggering. Circuit layout area is saved without the need of a timeout circuit associated with releasing a device maintaining a trigger state (i.e., a trigger latch). A RC time constant for triggering is set in an operational context according to conditions of usage and desired application of the ESD protection circuit.
