Patent CA-2273784-C (CA)
Inventor: HARPER JOHN ANTHONY
IPC: H04W4/00
Filed: 1997-12-04
Granted: 2005-03-01
Abstract: A satellite communications system provides a communications service to a mobile terminal (2) on which different communications applications (4a to 4d) may be run. Calls are set up between any of the applications (4a to 4d) via a satellite (12) to a network management centre (18) which provides different service adaptors (20a to 20d) which adapt the calls to different types of service provided over terrestrial networks (22), such as telephony, facsimile, internet or ATM services. The bandwidth allocated to each call over the satellite link may be varied during the call according to demand either from the relevant application (4) or from the network management centre (18). Multiple calls may be connected concurrently to or from different applications running on the mobile terminal. A maximum bandwidth is allocated to each call. Efficient use is thereby made of the limited bandwidth available over the satellite (12), according to the instantaneous bandwidth requirements of different applications (4). For real-time calls requiring multiple slots per frame in a TDMA channel, the slots are mutually spaced apart to reduce delay.

Abstract: A proximity sensor with an emitter capable of emitting energy waves of a selected wavelength and a detector capable of detecting energy waves with the selected wavelength, for example, energy waves in the infrared spectrum. The emitter and the detector are located in close proximity to one another on a single printed circuit board. When an article to be detected (e.g., any seed used in agriculture) passes the proximity sensor, the energy waves emitted by the emitter are reflected off the article and detected by the detector. The proximity sensor can be attached to a single wall of a container or to the side of a chute in order to detect the presence of articles in the container or to detect the passage of articles through the chute.

Title: Preconditioning spins near a nuclear magnetic resonance region
Inventor: SPEIER PETER
IPC: G01R33/44
Filed: 1999-10-19
Granted: 2004-08-31
Abstract: A method and an apparatus for obtaining NMR measurements are disclosed. An NMR measurement apparatus, the measured sample, or both elements may be subjected to motion during the measurement. The envelope of an RF carrier signal is modulated according to an envelope to generate a first sequence of RF pulses. The envelope, the phase of the RF signal, and/or a static magnetic field may be varied during the radiation of the first sequence to substantially saturate a first region of the sample.  The first sequence may include additional RF refocusing pulses that, when coupled with movement of the NMR measurement apparatus or sample, may also be used to substantially saturate the first region. A second sequence of RF pulses is radiated to establish a resonance region within the first region and measure an attribute of the sample.

Abstract: A dispensing machine is used to dispense rectangularly shaped containers including milk cartons and the like, preferably of a size ranging from approximately one-half liter to approximately two liters or even larger. The machine can be used to dispense various products including juices, soft drinks, milk, candy and virtually any product that can be suitably contained in a square rectangular container. The machine has a vertical channel containing paddles where each paddle supports only some of the containers in the channel when the channel is filled with containers. Since the containers have flexible side walls, the paddles move simultaneously to gently lower the containers one space at a time when the machine is activated. Also, when the containers are in the vertical channel, the lowermost container is not subjected to the weight of all of the containers above it when the channel is filled with containers. This arrangement prevents containers in the vertical channel from being crushed by containers located above it. In a further embodiment, a dispensing machine has three sets of shelves, each set having a vertical channel with control means so that three different types of products can be dispensed from one machine.

Abstract: A system for estimating a velocity of a stress wave induced in an unfinished wood product such as a log or tree stem is used to maximize the value of wood products produced. An accelerometer is placed against the log while the log is struck with a pneumatic hammer. By monitoring the signals received at the accelerometer, the velocity of stress wave can be determined. Based on the velocity, an estimate of the modulus of elasticity (MOE) for the wood in the log is made. A price table is selected that relates different sizes of lumber having the determined modulus of elasticity to a current market value. The log is then cut such that the value of the lumber produced is maximized.

Abstract: The aim is to effectively remove the unpleasant raw odor that is characteristic of soybeans and provide a high quality processed soybean food product. In a production method for processed soybean food products that includes a grinding step (A) in which raw soybeans are ground to obtain a soybean slurry and a heating step (B) in which the obtained soybean slurry is heated and thermally denatured, a deaeration step (C) for removing air bubbles mixed in with the soybean slurry is performed partway through the heating step (B). It is preferable that the heating step (B) and the deaeration step (C) are performed continuously. These steps can be effectively performed using a soybean slurry thermal deaeration device 1 provided with a first heating apparatus 10 for raising the temperature of the soybean slurry to a predetermined intermediate temperature; a deaeration apparatus 20 for deaerating the soybean slurry once it has reached the intermediate temperature in the first heating apparatus 10; and a second heating apparatus 30 for completing the thermal denaturation by further heating the soybean slurry once it has been deaerated in the deaeration apparatus 20.

Abstract: The functioning of the leach field (40) of a septic tank (20) type sewage system is maintained or rejuvenated by flowing air or other active gas into the system's conduits (34, 56), for instance, leaching chambers or perforated pipes in stone filled trenches. Differential pressure created by an air mover (71) forces air or other active gas to flow through the soil (38) adjacent the conduits (34), to an extent sufficient to push water from any saturated soil and engender desirable aerobic biochemical conditions in the soil. In alternate embodiments, conduits may be pressurized or evacuated. Valves (70) and other plumbing (68 ) are provided to control air flow and enable continued function of the sewage system during air flow treatment. Auxiliary piping is buried adjacent the trenches of the leach field and pressurized or evacuated to cause air flow through the soil and or the conduits of the leach field.
