Inventor: MEHRAD FREIDOON
IPC: G11C16/02
Filed: 1996-08-30
Abstract: An extended-life method for soft-programming at least one floating gate memory cell (10) includes connecting the substrate and the source (11) to a reference voltage, then applying to the control gate (13) a soft-programming voltage, the soft-programming voltage being between thirty and sixty percent of the voltage used to hard-program the cell. Increasing voltages are applied to the drain (12), while measuring the current flow into the drain (12). A specific drain (12) voltage, less than or equal to that value of drain (12) voltage at which the current flow into the drain (12) reaches a first peak, is chosen. With the substrate at reference voltage, the cell (10) is soft-programmed by applying to the drain (12) a first voltage slightly less than or equal to the specific drain (12) voltage; by applying to the source (11) a non-negative second voltage less than the specific drain (12) voltage; and by applying to the control gate (13) a third voltage no greater than the soft-programming voltage.

Abstract: In a radio selective calling receiver, a receiving unit extracts a digital signal from a radio signal received through an antenna. A frame synchronization signal detector frame-synchronizes the digital signal output from the receiving unit and outputs a state signal representing a frame synchronization state as one of a pull-in state and a pull-out state. A timer resets a timer value to start a timer operation when the state signal from the synchronization signal detector represents a change from the pull-in state to the pull-out state, and stops the timer operation to output a timer value when the state signal from the synchronization signal detector represents a change from the pull-out state to the pull-in state. A first memory sequentially stores a plurality of timer values from the timer. A second memory stores a reference value calculated on the basis of an average value of the timer values stored in the first memory. A third memory stores in advance data necessary for the radio selective calling receiver. A controller compares a timer value of the timer under operation with the reference value stored in the second memory and resets receiver data using the data stored in the third memory when a comparison result represents a coincidence.

Abstract: The method involves using an optical arrangement to measure the height of the separated letters (SE). If a sudden change in height is detected by the optical measurement system as the letters pass though under repeated height measurements an overlap warning is generated.

Abstract: A digitally-controlled oscillator (DCO) (60), such
as may be used in clock generator or clock recovery
circuitry in an integrated circuit, is disclosed. The
disclosed DCO (60) is a single-stage oscillator including
a variable load implemented as a binary-weighted array of
switched capacitors (40). Each of capacitors (40) has a
plate connected to a common node (X), and a plate that
receives a signal corresponding to one bit of a digital
control word (DCOCW). The common capacitor node (X) is
also connected to the input of a Schmitt trigger (42)
that produces the output clock signal (OUTCLK) and a
feedback signal that is applied to logic (38, 39) that
inverts the common node of the capacitors (40). The
switching time at the input of Schmitt trigger (42)
depends upon the variable load presented by the array of
switched capacitors (40), which is controlled by the
digital control word (DCOCW). As a result, the clock
signal (OUTCLK) is digitally synthesized by a single
stage of the DCO (60). A digital phase-locked loop (PLL)
clock generator circuit (50) including a phase detector
(64), digital loop filter (62) in combination with the
DCO (60), and a programmable frequency divider (66)
providing a feedback path from the output of the DCO (60)
to the phase detector (64), is also disclosed. The PLL
clock generator (50) may be used in an integrated circuit
such as a digital signal processor (30) or
microprocessor, and is particularly well-suited for use
in a battery-powered portable electronic system (200).

Abstract: A desk stand (40) for a hand-held computer (16) allows both variation in viewing angles of the computer display, and the ability to connect the computer to external, peripheral devices. The stand allows clearance for the computer to mate with a docking port (14) which in turn connects to peripheral devices such as a modem or a printer. Thus, the capabilities of the computer are greatly expanded. In addition the computer can be positioned on the stand to allow easier access to its input tablet. Thus, both right-handed and left-handed persons can position the computer so that data entry is more convenient. Moreover, the computer can be positioned in a manner that reduces glare on the computer display unit.

Abstract: Apparatus and method for controlling establishment of telecommunications call connections in a telecommunications network. The network comprises a plurality of switches each with its own switching processor means, and a plurality of switching processing platforms each comprising at least one call processor. The switches and switching processing platforms are interconnected by a data network. SS7 signaling messages are received in one of the platforms and a call is assigned to a call processor. The call processor communicates with one or more switching processor means for controlling establishment of the call. Call features are processed under the control of the call processor. Advantageously, any call processor can be used for serving any call in the network and can control all legs of a multi-leg connection. Advantageously, in a large network, the number of platforms may be significantly less than the number of switches which reduces the cost and complexity of administration of the network.

Abstract: A method for monocrystalline epitaxial deposition
which reduces the occurrence of large area defects for
chemical vapor depositions carried out at near
atmospheric pressure. Reactant gas is passed over a
semiconductor wafer (W) in a reaction chamber (14) to an
exhaust (22) in a conventional manner. A venturi tube
(46) in fluid communication with the reaction chamber is
adjusted to draw a vacuum pressure in the reaction
chamber (14). The relatively small vacuum pressure
produces a more laminar flow of reactant gas leaving the
reaction chamber. Reduction in turbulence and eddy
currents reduces the possibility that particles from
matter deposited near the exhaust of the reaction chamber
(14) can be transported upstream in the gas flow onto the
wafer, causing large area defects. A system (10) for
carrying out the method is also disclosed.

Abstract: A radio communication apparatus for transmitting
speech data by encoding and compressing data, and
multiplexing in a TDMA/TDD method has developed to
have automatic answering function wherein the received
speech data (compressed data) is stored in a semiconductor
memory and reproduced thereafter when the user
wishes. The tone quality of the received speech data
is detected on the basis of the received control data,
and the parameter indicating the tone quality is
recorded together with the speech data. The recorded
speech data is reproduced in accordance with the
parameter. Such parameters as unique word error
indicating no synchronization in the speech data and
CRC error indicating the occurrence of some error in
the received speech data are used as the parameter.
When the unique word error occurs, speech data all the
bits of which are "0" is used for the speech data.
When the CRC error occurs, the decoded speech data may
be suppressed. The defect speech data including the
error which occurs in the data transmission can be
prevented from being reproduced with no compensation.
