Title: Rod-type conveyor
IPC: B65G15/30
Filed: 1984-02-09
Abstract: A longitudinally elongate conveyor belt is adapted for conveying a plurality of transversely spaced items (OL, IL). The belt comprises a plurality of interconnected, generally transversely extending rod members (110) which are spaced apart along the longitudinal direction. Each rod member (110) is upwardly arched to define first and second item-supporting segments (116, 118).

Title: Spatial division multiple access wireless communication systems
Inventor: ROY RICHARD H
IPC: H04W16/28
Filed: 1992-11-24
Abstract: A method and apparatus for increasing the capacity and quality of wireless communication between a plurality of remote users and a base station is disclosed. Using measurements from an array of receiving antennas at the base station, parameters of multiple signals transmitted to the base station from a plurality of users in the same channel are calculated and used to obtain the positions and velocities of the users. The locations and other related signal parameters are used to calculate appropriate spatial demultiplexing strategies, reconstructing the individual transmitted signals from the receiver measurements and reducing interference to acceptable levels. This heretofore unavailable location information is used in solving the hand-off problem. This information is also used to calculate an appropriate spatial multiplexing strategy for simultaneous transmission of signals to users in the same channel. This can be the same as or distinct from the aforementioned receive channel. In combination, the transmit and receive systems establish multiple full-duplex links in the same channel by directively receiving and transmitting signals at the base stations only. This invention can also be implemented at the mobile sites to improve signal quality and to establish point-point communication links between multiple mobile users. Furthermore, implementation of both transmit and receive functions at the base station is not required. A receive-only system base station will still improve received signal quality and therefore capacity in addition to mitigating the hand-off problem.

Title: Hearing aid compatible piezoelectric speaker
Inventor: STERN TRAMPAS B
IPC: H04R25/00
Filed: 2000-02-11
Abstract: A piezoelectric speaker is provided which provides a magnetic field to couple the speaker to a hearing aid coil. The magnetic field induces a current in the hearing aid coil as it appears as a time varying magnet field to the coil. The time varying magnetic field is preferably proportional to the movement of a piezoelectric member of the piezoelectric speaker so as to induce a current in the hearing aid coil proportional to this movement. Such a magnetic field may be provided by connecting a magnetic material to the piezoelectric speaker such that motion in the speaker results in motion of the magnetic material, preferably at the position of maximum displacement of the speaker. Thus, the piezoelectric speaker may provide hearing aid compatibility.

Title: System, coding section, arrangement, coding apparatus, and method
Inventor: WILLEMS FRANCISCUS MARIA JOANN
IPC: H03M7/42
Filed: 1997-07-08
Abstract: Known systems use two probability signals for coding an input signal into an output signal and for decoding said output signal into the input signal. In a first memory field two probability signals are stored, and in a second memory field two other probability signals are stored, and in response to a further received symbol processor means adapt the probability signals. Such a system needs a giant memory capacity, which can be reduced by combining probability signals into a first combination signal to be stored in the first memory field and by combining further probability signals into a second combination signal to be stored in the second memory field, and by converting a third combination signal into at least one probability signal just before (de)coding takes place. <IMAGE>

Title: Method and apparatus for symmetrically modulating a controlled series compensation system

IPC: H02J3/18
Filed: 1993-05-17
Abstract: The invention relates to a method and to a device (4) for generating a synchronisation signal (Ss) for a control unit (drive unit) (6) for driving a converter valve (18) of a controlled series compensator (2). According to the invention, a sinusoidal equivalent variable, which may be either a measured line current (iL) or the sum of a capacitor current (ic) and of a valve current (iTh), the zero crossings of this equivalent variable not changing, is modified in terms of its phase angle in such a manner that a synchronisation signal (Ss) is available to the control unit (6), which synchronisation signal (Ss) corresponds to the phase angle of the capacitor voltage (uc) of the series capacitor (14) of the controlled series compensator (2). Thus, even in the bypassed state, a sinusoidal synchronisation signal (Ss) is obtained whose zero crossings do not change, as a result of which operating stability problems in the transient state during operation close to resonance no longer occur. <IMAGE>

Abstract: A laser surgery system having a computer control system coupled to a laser subsystem and a patient seat. The control system is coupled to the laser through a laser alignment system. The control system can be coupled to the patient seat through a patient alignment system. The control system sends a nominal position signal to move the patient seat, laser subsystem, or both so that the patient's first eye is moved into substantial alignment with the laser beam axis. The control system can send a second nominal signal to move the patient's second eye into substantial alignment with the laser beam axis. The control system can optionally comprise both an operator display and an assistant display. The assistant display provides real-time information to an assistant positioned at an assistant station adjacent the patient seat.

The control system can comprise an operator input for providing a pre-determined secondary ablative treatment. If it is determined that the first ablative treatment did not completely remove the epithelial layer from a target region, the operator actuates the operator input to deliver the secondary ablative treatment.
