Abstract: An integrated circuit (1) employing quantized feedback is capable of compensating for decay in received capacitively-coupled digital signals (S D ). In an exemplary embodiment, the integrated circuit includes a quantized feedback receiver (20) connected to a capacitively-coupled integrated circuit input (10). The capacitively-coupled input produces a decaying signal (S D ) for corresponding intervals of an input digital signal (S I ) that are substantially DC voltages. Longer sequences of consecutive data bits of the same logic state in the input signal are represented by a corresponding longer DC voltage signals resulting in a greater decay in the capacitively-coupled signal. The receiver operates by generating a complementary feedback signal (S F ) which is combined (in 35) with the capacitively-coupled signal (S D ). The feedback signal (S F ) is generated with a magnitude rate of change that compensates for the decay in the capacitively-coupled signal (S D ) such that the digital information in the combined signal (S C ) can be detected substantially without error due to the decay.

Abstract: Apparatus for detecting skin areas in video sequences includes a shape
locator and a tone detector (both in 12). The shape locator analyzes the input video
sequences (26) to identify the edges of all the objects in a video frame and determine
whether such edges approximate the outline of a predetermined shape that is likely to
contain a skin area. Once objects likely to contain skin areas are located by the
shape locator, the tone detector examines the picture elements (pixels) of each
located object to determine if such pixels have signal energies that are characteristic
of skin areas. The tone detector then samples pixels that have signal energies which
are characteristic of skin areas to determine a range of skin tones and compares the
range of sampled skin tones with the tones in the entire frame to find all matching
skin tones. An eyes-nose-mouth (ENM) region detector is optionally incorporated
between the shape locator and the tone detector to identify the location of an ENM
region on an object that is likely to be a face, so as to improve the accuracy of the
range of skin tones that are sampled by the tone detector.

Abstract: A motor system (100) having a stationary assembly (104)
including a winding and a rotatable assembly (106) in magnetic coupling
relation to the stationary assembly. A power supply link (132,136,140)
having upper and lower rails supplied by a power supply (134) provides
power to the motor winding. The power supply link has power switches
(132) responsive to a motor control signal for selectively connecting the
rails to the winding to energize the winding with a motor current whereby
an electromagnetic field is produced for rotating the rotatable assembly.
The power switches include a set of upper power switches and a set of
lower power switches. Each of the power switches has a conducting state
and a nonconducting state. The system includes a disable circuit
(172,174) for selectively generating a disable signal and a control circuit
(122) for generating the motor control signal to control the power switches
(132). The control circuit is responsive to the disable signal for
controlling the power switches so that the lower power switches become
conducting and the upper power switches become nonconducting, or vice-versa,
thereby deenergizing the winding to disable the motor. Other
features are also disclosed including circuitry for commutating the motor
in advance of zero crossings of the back electromotive force, correcting
asymmetries in the commutation intervals and reversing the motor.

Abstract: A piston-type fluid displacement apparatus includes a housing enclosing a crank chamber,
a suction chamber, and a discharge chamber. Discharge conduits are formed at a top dead center
position of the piston. A control device includes valve members having suction apertures and
discharge apertures for opening and closing the suction conduits and the discharge conduits. The
control device further includes a driving mechanism joined to the valve members for driving the
valve members to gradually open each of the suction conduits during the suction stage of the
piston and to gradually close each of the discharge conduits during the discharge stage of the
piston. Thus, the piston-type fluid displacement apparatus may prevent the valve assembly from
stopping or sticking at the sliding contact surfaces of the suction and discharge holes to allow the
pistons to reciprocate smoothly within each cylinder without reducing the compression efficiency.
Further, the piston-type fluid displacement apparatus also improves the sealing performance
between the valve assembly and the sliding contact surfaces of the suction and discharge holes.
