摘要:
Aerosol and hydrosol particle detection systems without knowledge of a location and velocity of a particle passing through a volume of space, are less efficient than if knowledge of the particle location is known. An embodiment of a particle position detection system capable of determining an exact location of a particle in a fluid stream is discussed. The detection system may employ a patterned illuminating beam, such that once a particle passes through the patterned illuminating beam, a light scattering is produced. The light scattering defines a temporal profile that contains measurement information indicative of an exact particle location. However, knowledge of the exact particle location has several advantages. These advantages include correction of systematic particle measurement errors due to variability of the particle position within the sample volume, targeting of particles based on position, capture of particles based on position, reduced system energy consumption and reduced system complexity.

A network device is provided which includes a device input, at least one port, a frequency doubler, a data I/O device, and a programmable delay locked loop. The frequency doubler is coupled to the input and configured to receive an input signal and output an output signal having double the frequency of the input signal. The data I/O device is configured to output data based upon a reference clock signal. The programmable delay locked loop is coupled to the device input and configured to receive an input signal and to automatically output an output signal being a predetermined amount out of phase from the input signal. An external clock signal received at the device input is input to the frequency doubler. The output of the frequency doubler is input to the data I/O device as a reference clock. Data (e.g., from internal device logic) is output from the data I/O device to the at least one port. The external clock signal is input to the programmable delay locked loop, which outputs an output clock signal having a frequency equal to the frequency of the external clock signal, in synchronization with the data being output.

A nitride layer is deposited over a field oxide layer used to separate transistors formed in a substrate, the nitride layer serving to decrease transistor current leakage. The nitride layer has a dense lattice, effectively blocking H+ and Na+ penetration from overlying layers into the field oxide. Positive ions such as H+ and Na+ penetrating into the field oxide layer cause a p-substrate under the field oxide layer to become inverted or act like an n-type substrate, creating leakage current between source and drain regions of transistors which the field oxide layer separates. When high transistor threshold voltages such as 12 volts or more are desired, the nitride layer provides a significant reduction in current leakage.

Depletion mode pass gates utilized in a PLD to enable a gate voltage of Vcc to be applied for turn off, as opposed to a higher voltage required for enhancement type devices. With Vcc applied for turn off, gate oxide stress is reduced and chip reliability increased. A decoder utilizing PMOS transistors is further used to supply a negative gate voltage to enable turn off of the depletion mode pass gates. In one embodiment, to prevent pumping the power supply voltage above Vcc when supplying Vcc to gates of the pass gates, the decoder is an all PMOS device using PMOS transistors to connect Vcc to gates of the pass gates. In another embodiment both NMOS and PMOS transistors are utilized, with PMOS blocking transistors utilized to prevent a negative voltage from being applied to the NMOS transistors and causing current leakage. A negative voltage pump is further provided to supply a sufficient negative voltage.

A customer is alerted to the availability or completion of service by a service provider through communication with a wireless terminal of the customer. The terminal has an assigned identification number and a control channel, and as a first step, the identification number (e.g., telephone number) of the wireless terminal is registered with the service provider. When service for the customer is available or completed, a determination is made of whether the wireless terminal is active. If active, the customer is alerted to the availability or completion of the service, preferably using a preformatted message transmitted to the wireless terminal over the control channel. In one example, the service provider is a restaurant and the customer is alerted to the availability of a table.
