Patent CA-2156912-A1 (CA)
Title: Improvements in and relating to measurement of fluid flow velocity
Inventor: REYNOLDS PATRICK JOHN
IPC: G01F1/704
Filed: 1994-03-14
Abstract: The invention provides an improved method and apparatus, for measuring gas flow velocity. The invention is particular well suited for use in measuring flow velocity of noxious and/or explosive gases in a corrosive environment such as landfill sites. Gas flow velocity is measured by varying the energy content of a volume of gas at a first preselected point (18) thereby creating a thermal label in a flow path (1) and detecting the said variation in energy at subsequent preselected points (34) in the flow path. The time taken for peaks of these thermal labels to pass detectors (34) enables flow velocity to be calculated. This may be achieved by a computer at a remote position. Preferably the energy content is reduced by injecting an amount of liquefied gas (17) into the gas flow path. The invention avoids the use of heaters and there is therefore no risk of sparks occurring which may ignite explosive gas mixtures.

Title: Hand held data collection computer terminal having power management architecture including switchable multi-purpose input display screen
Inventor: DANIELSON ARVIN D
IPC: G06F3/02
Filed: 1995-09-19
Abstract: A portable data collection terminal has an elongate housing with a hand grip conforming rear surface. A front surface features a numerical keyboard adjacent a lower end of the housing and an LCD screen adjacent the keyboard toward an upper end of the housing. The display screen is of elongate rectangular shape, its length extending longitudinally of the housing of the data terminal. The active area of the display screen is covered by a touch sensitive overlay screen which is configured in one mode of operation of the data terminal into an alphabetical keyboard. The orientation of the display is switchable between orientations in which the line direction of the displayed data extends across or longitudinally of the data terminal. The keys of the numerical keyboard are identified by indicia disposed on a template. The orientation of the template may be sensed to switch the orientation of the displayed data and touch sensitive key identifiers to correspond to the orientation of the indicia on the template. As a further embodiment an electromagnetic activation by a pen may be used to enter data into a data terminal. Power saving shutdown extends the battery life of the data terminal. A shutdown mode permits resumption of operations by depression of a key. During operations power consumption is reduced by efficient distribution of operations control between microprocessors. The microprocessors have shared access to and control of system operations.

Patent CA-2161961-A1 (CA)
Title: Angular position encoder
Inventor: DAMES ANDREW NICHOLAS
IPC: G06M1/10
Filed: 1994-05-03
Abstract: In an apparatus for indicating the angular position of a rotatable member, a drive coil (51) is provided with its axis corresponding to the axis of rotation of the rotatable member. A coil (65) is wound around the rotatable member, and a capacitor (66) is provided in the coil (65) to form an LC resonant circuit. The coil (65) on the rotatable member is wound so that application of an alternating magnetic field to the drive coil (51) induces a resonance in the LC circuit which is constant for all angular positions of the rotatable member. Pick-up coils (53, 55) ace provided such that the planes of these coils and the drive coil (51) are orthogonal. The resonance of the LC circuit produces signals in the output coils (53, 55) which depend upon the angular position of the rotatable member. The signals may be processed to determine that angular position, and the processing is simplified with this arrangement of output coils since the signals produced therein are quadrature signals.

Title: Time Interval Measurement System and a Method Applied Therein
Inventor: MURAKAMI HIROKUNI
IPC: H03K21/00
Filed: 1996-07-30
Abstract: In order to measure an individual time interval with accuracy be-yond frequency limit of semiconductors, a time measurement system of the invention generates a series of delayed pulses, each of which has the same pulse width with the time interval to be measured and delayed by a unit delay time shorter than a cycle time of a system clock from its preceding delayed pulse.    A series of discriminate number measurement pulses are also gen-erated from the series of delayed pulses, each of which rises at a com-mon time and falls at each corresponding delay pulse.    From number of a longest sequence of the same pulse number of the system clock counted in the discriminate number measurement pulses, the unit delay time is measured.    From average value of pulse numbers of the system clock counted in each of the delayed pulses, the time interval to be measured is cal-culated with accuracy of the unit delay time.
