Filed: 1996-03-26
Abstract: A two-channel metal detector system (32) disposed
adjacent the crop feed path of a harvester (10) to detect
ferrous metal objects in the crop material is provided with
both positive and negative adaptive detection thresholds
(ADAPT.POSTH, ADAPT.NEGTH) for each channel, the thresholds
being independently varied according to the average
positive and negative peaks of the noise component in the
channel output signals. A channel output signal (CH0, CH1)
is sampled and digitized and the positive and negative
peaks (POSPK, NEGPK) of the noise component occurring over
fixed time intervals are filtered to provide average
positive peak and average negative peak values (L/RPOSF and
L/RNEGF) that are stored in an E 2 PROM and updated according
to long term variations in the noise component. The
positive and negative adaptive detection thresholds
(ADAPT.POSTH, ADAPT.NEGTH) are set according to the average
positive and negative peak values (L/RPOSF, L/RNEGF) and
the adaptive detection thresholds are compared with the
sample channel output signal (CH0, CH1) to determine if a
ferrous metal object has been detected. By storing the
average positive and negative peak values (L/RPOSF,
L/RNEGF) of the noise component in an E 2 PROM memory, the
adaptive detection thresholds and the filters (82) may be
initialized at system start-up to the values existing at
the time of system shut-down.

Title: Missile fuzing system
Inventor: SEBANY JOSEPH L JR
IPC: G01S13/44
Filed: 1996-06-28
Abstract: A fuzing system in a guided missile (12) generates a
detonation signal for a warhead (14) carried by the missile (12).
The missile (12) has a seeker/tracker (20) to track and direct the
missile (12) towards a target (16). The seeker/tracker produces
a signal representative of the angular deviation (LOS) between the
target (16) and the missile (12), and a signal (RM) representative
of a range between the target (16) and the missile (12). In
response to these signals, a guidance/fuzing computer (26)
produces a time-to-go signal, t go  where t go , relates to the range
between the missile and the target divided by the rate of change
in such range, such time-to-go signal representing the time
remaining before the missile intercepts the target, and a miss
distance signal representative of a predicted distance, normal to
the line of sight (30), at the time the remaining before the
missile intercepts the target. A fragment velocity signal is
provided representative of the velocity of fragments of the
warhead, and the computer (26) produces the detonation signal in
response to the miss distance signal and the fragment velocity
signal.

Abstract: The refrigeration system according to the invention
includes a vacuum jacketed pressure vessel which contains both
a spray heat exchanger and a shell and tube heat exchanger.
The spray heat exchanger includes one or more nozzles for
directing a first refrigerant at a heat exchanger element
conveying a second refrigerant. The first refrigerant is
sprayed in a fine mist from the nozzles onto the heat
exchanger element conveying the second refrigerant. The first
refrigerant then evaporates and cools the second refrigerant
within the heat exchanger element. The shell and tube heat
exchanger is a counter current heat exchanger which includes
an inner tube for conveying the second refrigerant to the
spray heat exchanger, and an outer tube surrounding the inner
tube for conveying the first refrigerant recovered from the
interior of the vacuum jacketed pressure vessel out of the
pressure vessel. The spray heat exchanger recovers the heat
of vaporization of the primary refrigerant, while the shell
and tube heat exchanger recovers the enthalpy remaining in the
evaporated first refrigerant.

Abstract: The method involves passing the input speech through a preprocessor into a speech processing unit, where it is subjected to a speech recognition process. The preprocessor extracts characteristics from the input speech, segments and classifies it according to the energy content, and only passes the segments whose energy content exceeds a defined or adaptively determined threshold. Each segment whose energy content exceeds the threshold is finally investigated, and classified as to whether it is derived from a speech or non-speech signal. Only those segments derived from speech signals are processed further.

IPC: G11B19/02

Abstract: The mechanism for loading and unloading a disk cartridge (13) uses
two sliders (70, 73) (one on each side of a base plate (46)), which move in
opposite directions under the influence of a tiller (76). Each slider (70, 73)
has a slot (262, 281) to receive one of the two lifting pins (136, 139) provided
on the cartridge receiver (82). The movement of the sliders (70, 73) drives
the lifting pins (136, 139) along the slots (262, 281), thereby raising or
lowering the cartridge receiver (82) depending upon the direction of rotation
of the tiller (76). The sliding motion of the lifting pins (136, 139) engaged in
the S-shaped slots (262, 281) thus unloads a disk (14) from or, alternatively,
loads the disk (14) onto the drive spindle (61). As the lifting pins (136, 139)
travel along their respective slots (262, 281), the lifting and lowering of the
disk (14) is accomplished in such a manner that the disk hub (15) is peeled
from the spindle magnet (63) rather than being lifted vertically off the spindle
(61). This reduces the peak force required to break the magnetic clamp force
between the spindle magnet (63) and the disk hub (15). In this system, the
dust door (91) is attached to the cartridge receiver, and the label end of the
loaded cartridge (13) remains visible when the disk (14) is loaded. This
system may include a bias coil assembly (94) rotatably mounted on an arm
(97) so that the bias coil assembly (94) may be loaded into or extracted from
the disk cartridge (14) and placed out of the travel path of the disk cartridge
(14). The rotation of the bias coil arm (97) is effected by one of the sliders
(70, 73).

Abstract: The present invention realizes a rapid and efficient cell search and
small-size instrument for an asynchronous DS-CDMA cellular system.
This cell search detects the correlation between the received signal and the
short code of the control channel, and matched filter 22 detects the
maximum electric power correlation peak location. Next, using
correlators 28-1 to 28-n which are parallelly set in a plurality for RAKE
processing with plurality, identifies the long code that is set in the
system with the detected long code timing. After the long code is
synchronized, a multipath signal is received using 28-1 to 28-n, and the
data is judged by RAKE processing. When peripheral cell search is
executed, after long code timing is detected by using matched filter 22, the
long code of the candidate peripheral cell is designated using the same
matched filter. Handover is safely realized by receiving the signal from
the connected base station by correlators 28-1 to 28-n, and the base station
signal through handover by 22.

band, the composite signal is received and applied to a

signal, which is in a discrete form, is subtracted from
