Title: Vector fm modulator
Inventor: BARABASH DARRELL W
IPC: H03C1/50
Filed: 1992-10-16
Granted: 2003-04-29
Abstract: A cellular-telephone transmitter (10) employs a vector modulator (14). An integrating circuit (52) generates the integral of the message signal and applies it to circuitry (54, 56) for generating in-phase and quadrature modulation signals representing the cosine and sine, respectively, of the integrating-circuit output. The vector modulator (14) produces the desired FM signal by adding together quadrature and in-phase versions of a carrier in proportion to the values that the quadrature and in-phase modulating signals represent.

Abstract: The invention herein provides a method and apparatus for inspecting a bonded joint between components.   A cross-sectional image of the joint is analyzed by determining the location of  a  first  characteristic  of the  joint,  the centroid of the joint in the cross-sectional image; and then measuring a second characteristic of the joint in reference  to  the  location  of  the  centroid.    This measurement  may  be  used  by  comparing  it  with  a predetermined specification expected for the measurement for the purpose of determining the quality of the joint. The invention is particularly advantageous for studying cross-sectional  X-ray  images  of  solder  joints  between electronic components and substrata upon which they are mounted and can be implemented for analyzing the images produced in cross-sectional X-ray inspection machines such as  scanned beam X-ray  laminography  systems or digital tomosynthesis systems.

Abstract: A cardiac pacemaker having an automatic pulse rate response gain factor responsive to at least one cardiac-related physiological characteristic of, a patient. The pacemaker includes a rate controller that comprises a detector nor detecting a plurality of individual measurements of at least one physiological characteristic over each of a plurality of pre-determined time periods, with each of the individual measurements being an average of values detected over each of a respective multiple number of incremental time periods occurring within each of the pre-determined time periods. The pacemaker saves the highest measurement from one incremental time period of each of several consecutive pre-determined time periods, and these highest measurements are averaged. Thereafter, the rate controller adjusts the rate response gain factor or slope of the pulse rate in relation to the physiological characteristic measurement and a pre-determined target pulse rate. In a preferred embodiment, two physiological characteristics are measured, with high values averaged of only one characteristic when that characteristic exceeds a threshold level of the other characteristic. One embodiment is pulse rate responsive to minute volume measurement in combination with accelerometer measurement, with accelerometer measurement requiring a threshold value over an increment of time prior to minute volume recordation for input toward rate response gain factor.
Patent CA-2138927-C (CA)

Filed: 1994-12-22
Granted: 2001-02-06
Abstract: The invention relates to a digital method of detecting pulses of short duration and an arrangement for implementing the method. A threshold value is generated by means of a statistical procedure which is common in radar engineering, by means of which short pulses to be detected can be differentiated as opposed to long pulses. The method includes sorting a predeterminable number of temporally consecutive signal samples by amplitude and creating a ranking of the signal samples. An associated amplitude value for a predeterminable rank within the ranking is determined and multiplied by a predeterminable weighting factor (k) so that an amplitude threshold value (SW) is generated. All signal samples whose amplitude is greater than the amplitude threshold value (SW) are then marked with a marking signal.

Abstract: This invention relates to a process for bonding a vehicle window to a vehicle flange comprising the sequential steps of: a) applying a liquid masking composition to a vehicle flange, b) painting the vehicle, and drying or curing the liquid masking composition sufficiently to form a strippable mask; c) removing the mask from the flange; and d) adhesively bonding the vehicle window to the vehicle flange. Such a masking process advantageously eliminates the need for the use of solvent-based primers normally used to prime a painted vehicle flange, and provides a mask which is more easily applied and removed from the flange than masking means which initially comprise a solid substance.

Granted: 2005-10-18
Abstract: In a global communication system comprising a constellation of satellite nodes that move with respect to each other, data packets are routed across communication links in a evenly distributed fashion. Uniform link usage is achieved within allowed routes determined by end to end transport delay criteria. The routing method computes routes in advance using an iterative process which selects routes for each source - destination pair from an allowed feasible set of alternative minimal hop routes by trying to equalize link usage probabilities for the links involved at each step of the route determination process. The routing method takes into account link failures and link and node shutdowns. Minimum hop routes are selected based on maximizing network routing entropy resulting in a uniform usage of the system's communication links. Directed randomization of routes between source - destination pairs of nodes is implemented to prevent link congestion while minimizing packet transport delay. Individual routing tables are generated and maintained in each satellite node.      The tables may be updated regularly to reflect changes in the traffic demand distribution and the physical node connectivity within the constellation which occur as a result of satellite motion and failures in the network.
