Patent CA-2361324-A1 (CA)
Title: Thermo-sensitive labels for beverage containers
Inventor: MOROSKAT JASON J
IPC: G01K1/14
Filed: 2001-11-14
Abstract: The invention provides a visual indicator relating to the temperature of the liquid within the beverage container. The invention consists of two distinct visual indicators.  The first indicator resembles a conventional beverage container and the second indicator consists of printed legends in the form of a cautionary warning and a salutation. These indicators have a thermo-sensitive coating, which will change in color depending on the temperature of the liquid inside the container. This feature is particularly valuable during large social gatherings wherein a communal cooler is used. This will help the allow the people attending the event an easy way to determine if their beverage is cold or if it is a beverage contributed by a late arrival. The label is not only practical for this application, but provides the users with an amusing effect.

Patent CA-2380392-A1 (CA)
Inventor: GROSS ERICH R
IPC: G01N21/35
Filed: 2000-07-12
Abstract: Percentage concentrations of constituents of a sample of cereal grain or other agricultural product in a flowing stream are determined while harvesting or processing using a short wave near infrared analyzer. The analyzer irradiates the sample, picks up diffuse reflectance of individual wavelengths from the sample and spatially separates the diffuse reflectance into a response at individual wavelengths. The result is to simultaneously detect the intensities of the individual wavelengths in parallel from the same portion of the product being analyzed. Percentage constituents of the composite substance may then be compared with known percentage constituents to determine the constituents in the sample product. The inventive wavelength analyzer is suitable for attaching to the agricultural combine to perform real time measurements in the field.

The apparatus is of particular use for a single trip sidetrack system in combination with an MWD-tool, a whipstock, and an anchor packer without a bypass valve.
Patent CA-2403562-A1 (CA)
Inventor: VARADI PETER
IPC: H02N2/00
Filed: 2001-03-21
Abstract: A single piezoelectric (22) is excited at a first frequency to cause two vibration modes in a resonator (24) producing a first elliptical motion (100a) in a first direction at a selected contacting portion (44) of the resonator that is placed in frictional engagement with a driven element (42) to move the driven element in a first direction. A  second frequency excites the same piezoelectric (22) to cause two vibration modes of the resonator producing a second preferably elliptical motion (100b) in a second direction the selected contacting portion (44) to move the drive element (42) in a second direction.  The piezoelectric is preloaded in compression by the resonator.  Walls of the resonator are stressed past their yield point to maintain the preload. Specially shaped ends on the piezoelectric help preloading. The piezoelectric can send or receive vibratory signals through the driven element to or from sensors to determine the position of the driven element relative to the piezoelectric element or resonator. Conversely, the piezoelectric element can receive vibration or electrical signals passed through the driven element to determine the position of the driven element. The resonator is resiliently urged against the driven element, or vice versa. Plural resonators can drive common driven elements.

Patent CA-2411437-A1 (CA)
Inventor: OWEN RAY
IPC: H01Q3/26
Filed: 2001-06-05
Abstract: An adaptive antenna array (14) includes a multiplicity of antenna elements (12a-12k, 48a-48k) responsive to uplink communications (16a-16k) and arranged to support directional-orientated downlink communication to subscriber units (18). The adaptive antenna array (14) is operationally responsive to a signal processor (28) that co-operates with direction of arrival estimation logic (36) to assess an angle of arrival of uplink communications incident to the array. To avoid inter-cell interference, especially during early stages of a call, the signal processor operates to ensure that a wide area downlink beam (108) is provided for a downlink path to an addressed subscriber unit. With time and/or with reported (68,84) downlink quality of service (QoS) metrics, the signal processor (28) regulates (74, 92, 96) a width of the downlink beam by altering the number of antenna elements used to support the downlink beam, thereby altering the downlink beam aperture. Generally, with time, more antenna elements (92) are used and so the beam is narrowed, although in-call fluctuations in downlink quality of service are dynamically addressed.
