Title: Negative feedback circuit to control the duty cycle of a logic system clock
IPC: H03K5/156
Filed: 1990-05-18
Abstract: A circuit for controlling the duty cycle of a high 
frequency logic system clock using negative feedback. A 
high-level buffer (18) used to drive the system clock bus 
receives the output of a crystal oscillator (40). The buffer 
output (50) is sampled by an integrator circuit which produces 
a voltage level corresponding to the duty cycle of the 
clock, and this voltage level is compared to a reference 
voltage using an operational amplifier (60). The op-amp output (70) 
is applied to the buffer input (75) as negative feedback to 
alter the bias level at the buffer input (75) in a way as to 
vary the point in the rising and falling transitions of 
the crystal oscillator (40) where the threshold of the buffer (48) 
is crossed. A circuit (52,54) monitors the clock signal output of 
a high-level buffer (48), and determines whether the duty cycle 
of the crystal oscillator (40) which drives the output buffer (48) 
should be increased or decreased. A corresponding DC bias 
to the input of the output buffer (48) causes the crystal 
oscillator (40) output to reach threshold levels of the output 
buffer (48) at different times during each clock pulse, thus 
adjusting the duty cycle of the buffer output (50). An RC 
integrator (52,54) is used to monitor the buffer output, and the 
output of this integrator is compared with a reference 
voltage in an operational amplifier (60). The output of the 
operational amplifier (60) biases the input (75) to the output 
buffer (48) to a level corresponding to a need to increase or 
decrease the duty cycle of the buffer output clock signal.

Title: Method and apparatus for measuring and controlling the level of hormones in an animal circulatory system
IPC: G01N33/74
Filed: 1990-11-20
Abstract: The relationship between the level of a hormone, such as the immune-regulating cytokine IL-1, in the blood stream of an animal and application of sensory stimuli to the animal is determined by periodically taking discrete samples of the animal's blood while the stimuli are applied, measuring the levels of the hormone in the discrete samples, and correlating these levels with the application of the stimuli. Thereafter, the level of the hormone is controlled by applying to the subject those stimuli that have been found to produce a desired effect on the level of the hormone in the blood. Biofeedback training and relaxation techniques are used to increase the effectiveness of the method and apparatus.

Title: Detection arrangement of railway vehicle wheels
IPC: B61L1/10
Filed: 1992-09-01
Abstract: In a wheel sensor for detecting wheels of railway vehicles, preferably for counting the wheels (6) in a section of track, metal-detecting, inductive sensors (1, 3, 41, 43) are attached symmetrically to travel rails (4) and their relative levels are evaluated, as a result of which interference influences of an electrical, inductive, thermal or mechanical kind are suppressed and flanged wheels can be distinguished from metal components which give the false impression of other wheels. Train types can be determined from the patterns (Fig. 4) of the signals (51, 55) when satisfactory wheels pass by and from metallic objects. The earliest arrival of the train at positions relative to the wheel sensor is calculated from the maximal speeds assigned to the train types. <IMAGE>

Abstract: Program data generated by the host system to be
used in programming one or more associated ISPLDs is
converted using a first interface from a parallel data
format to a serial data string and then transmitted
serially to a second interface. In one embodiment, the
first and second interfaces employ Universal
Asynchronous Receiver/Transmitter (UARTs). The
receiving unit converts the serial program data string
to a parallel data byte which is then provided to the
programming pins of the ISPLD desired to be programmed.
Signals indicative of information relating to the
operation of one or more of the ISPLDs associated with
the host system may be provided to the host system via
pin SDO of the asserted ISPLD. In this manner,
embodiments in accordance with the present invention
may utilize a two-wire transmission scheme, and thus
two-wire interfaces, to facilitate programming of the
associated ISPLDs. Having the capability to utilize a
two-wire transmission scheme, in turn, allows ISPLDs in
accordance with the present invention to be programmed
using wired transmission schemes such as for instance
coaxial, twisted pair, and coaxial as wells as wireless
transmission schemes such as for instance radio
frequency (RF) and infrared radiation (Ir).
