Abstract: A method of halftoning a digital gray scale image is disclosed that utilizes a point by point thresholding comparison to a novel diagonal correlation dither matrix. The new dither matrix forces diagonal correlation of adjacent dots in the output image while maximizing dispersion of dots, thereby producing visually unobtrusive output dot patterns. The matrix is generated according to a spatial domain cost function that determines a cost value for each candidate pixel based on respective radial distances and relative angles between a candidate pixel and the ON pixels in the matrix such that unit diagonals are favored over placement of vertically or horizontally adjacent dots.

Abstract: A system and method for controlling a peripheral bus clock signal through a master and/or slave device is provided that accommodates a power conservation (or "clock run") scheme in which a peripheral bus clock signal may be stopped, for example, by a power management unit or other central resource. The clock run feature is enabled or disabled by the system during or immediately following system initialization, based upon the ability of the peripheral bus components to support the clock run feature. The system includes status and command registers to provide an indication of whether each of the peripheral bus devices can support the power conservation scheme. The status and command registers both include a bit dedicated to the clock run function. The status register bit is set based upon whether that particular device can support the clock run function. After each of the dedicated status register bits is checked, the dedicated command register bit is set in each of the peripheral bus devices to either enable or disable the clock run feature.

Abstract: A system and method for providing personal communications services are disclosed. A bridging and signaling unit implements a bridge for connecting telephone calls between a caller, a called party, and an alternate destination. A caller who calls the personal telephone number associated with a called party is held at the bridging and signaling unit while waiting for a return telephone call from the called party. The called party is alerted to the existence of the call through a paging system. If the time period during which the caller is on hold exceeds a time-out period, the caller will be connected to an alternate destination, such as a secretary, an answering service, or a voice messaging system. If the called party places the return telephone call while the caller is connected to the alternate destination, the called party will be connected to the caller and the alternate destination in such a manner that that the called party can hear the conversation between the caller and the alternate destination, but the caller and the alternate destination cannot hear the called party and do not know that the called party has connected, i.e. the called party is on mute mode. After screening the call, the called party may then indicate that he/she wishes to be connected to the caller, at which time the connection to the alternate destination is terminated and the caller and the called party are connected such that they can speak with each other. If the called party does not wish to speak to the caller, he/she may hang up, and the connection between the caller and the alternate destination may continue.

Abstract: An automated sphygmomanometer which automatically determines when a blood pressure determination needs to be made. During a "guard mode" determination, a cuff on an appendage of the patient is frequently inflated to a check pressure, which is preferably below the patient's mean arterial pressure ("MAP"), and the signature (shape, amplitude, pulse period, etc.) of the measured oscillometric signal is compared to a stored signature of a portion of an oscillometric signal at a corresponding portion of the oscillometric envelope determined during a previous blood pressure determination. If these signals differ by some predetermined amount, it is determined that the patient's blood pressure has changed significantly and that a new blood pressure determination needs to be conducted immediately. These guard mode determinations are made in addition to the normal blood pressure determinations made at predetermined intervals typically selected by the user. In addition, the shape of the oscillometric signal is quantified during guard mode so that it is possible to discriminate oscillations on the diastolic side of a patient's oscillometric envelope from oscillations on the systolic side of the patient's oscillometric envelope, thereby preventing a large shift in the oscillometric envelope from going undetected.

Abstract: Cross-polarization cancellation apparatus, particularly useful in a frequency reuse system, includes a dual-polarized receiving system (22) that receives a first electromagnetic signal (on 23) having frequencies within a given frequency channel, which signal is transmitted from an external source at a first polarization (HOR). The receiving system also receives a second signal (on 25) having frequency components within the given frequency channel which was transmitted at a second, different polarization (VERT). Received cross polarized energy of the second signal is cancelled by employing an antenna for receiving the first and second signals and for providing first and second antenna output signals containing received energy arriving at the antenna at the respective first and second polarizations (HOR, VERT). A novel circuit arrangement (60, 36) applies the antenna output signals to a combiner (50) at an optimized relative amplitude and phase to substantially cancel the received cross polarized energy of the second electromagnetic signal.

Abstract: A display element is proposed for use in a magnetic theft-prevention system comprising the following elements: an elongated ductile magnetostrictive strip of amorphous ferromagnetic material which can be activated and deactivated by applying and removing respectively a bias magnetisation field Hbias and can in the activated state be stimulated by an alternating magnetic field to generate longitudinal mechanical resonance vibrations of resonance frequency fr. The mechanical stresses resulting from the resonance vibrations cause the magnetisation of the strip to change detectably. The display element is characterised in that: the material has a flat B(H) loop which is as linear as possible as far as the saturation region; a strip of the material has a magnetic anisotropy perpendicular to the strip length and the anistropy field strength HK is greater than the bias magnetisation field strength Hbias; and a strip of the material in the activated state of slight variation in a test bias magnetisation field strength Hbias = 6 Oe undergoes a change in the resonance frequency dfr in relation to the change in the bias magnetisation field strength dHbias of 400 Hz/Oe ≤ |dfr/dHbias| ≤ 800 Hz/Oe; and the strip in transition from its activated to deactivated state undergoes a change in the resonance frequency Δ fr ≥ 1.2 kHz.
