Patent CA-2420368-A1 (CA)
Inventor: DEMOORE HOWARD
IPC: F26B21/00
Filed: 2001-08-24
Abstract: A computer controlled power saving automatic zoned dryer for a printing press has a dryer head (36) facing the substrate travel path (P), having a multiplicity of IR lamps (60) connected individually or in groups to form a plurality of heating zones running longitudinally and each extending laterally side by side across the substrate travel path (P). The radiant heat output of each heating zone is controlled separately by means of a control unit (154) connected to a power supply. The control unit (154) individually regulates output of the heating zones. Unneeded zones are turned off to reduce cost of power and conserve energy. A plurality of heat sensors (35) spaced laterally across the substrate path (P) measure the surface temperature of substrate heated areas corresponding to the heating zones being operated and maintain an automatic set point temperature. The temperature of each individual heated area can be regulated automatically by adjusting the output of its heating zone whereby printed substrates (S) having a more even temperature profile are delivered. In an alternate manual mode any zone can be set independently to operate at any percentage of full available power from zero to 100%. Separate high velocity air scrubbers and additional air extraction (40) are used to enhance the total drying effect of the zoned dryer assembly.
Patent CA-2421542-A1 (CA)
Title: System and method for optical transmission
Inventor: TAJIMA AKIO
IPC: H04J14/00
Filed: 2003-03-11
Abstract: A system and method for bidirectional optical transmission in one optical fiber with large transmission capacity, enabling the enlargement of transmission distance. Downward optical signals sent from one or more downward optical signal transmitters are received by one or more downward optical signal receivers via an optical fiber transmission line and upward/ downward signal separating multiplexer - demultiplexers. On the other hand, upward optical signals sent from one or more upward optical signal transmitters are received by one or more upward optical signal receivers by following the opposite route. Output signals from the downward optical signal transmitter leak in the upward optical signal receiver via the upward/ downward signal separating multiplexer -demultiplexer. However, there is a large difference between the frequency of the upward optical signals and that of the downward optical signals, and beat/ noise components produced by interference in the two wavelengths are present outside the band of the upward optical signal receiver, thus avoiding the influence of coherent crosstalk. Additionally, power crosstalk also does not become a problem because of large isolation.

Abstract: A clip for retaining a trim cover assembly against a foam pad of a vehicle seat including a base having a hook end and a lock end. The base also includes a flange extending out therefrom. The hook end defines a hook, which secures the trim cover assembly to the clip. The lock end includes a lock and a lock hook. The foam pad includes a pair of inner foam pad walls that define a trench, through which the clip initially passes before contacting the foam pad. The clip is inserted into the foam pad so that the lock end passes completely through the foam pad to an underlying "B" surface. The lock hook is then rotated relative to the base until the lock hook engages the flange. The clip is firmly anchored within the foam pad by the lock end, which has a width greater than the trench.
Patent CA-2422900-A1 (CA)
Inventor: HANSSON HENRI
IPC: A23L1/09
Filed: 2001-10-24
Abstract: Dysglucaemia is treated and/or prevented by the administration of granulated starch, enzymatically degraded and releasing reducing sugars at a rate, adjusted to the metabolism of the patient, suffering from dysglucaemia. For example nocturnal hypoglycaemia in diabetic patients is prevented by administering to said patients a granulate or tablets comprising granulated cornstarch, and preferably also heat treated cornstarch and a low calorie sweetener. The inventive granulation minimises the available surface area and retards the enzymatic degradation of the cornstarch and ensures a controlled, e.g. a substantially linear release of reducing sugars, such as glucose, and a stable blood glucose level during several hours. The granulate or tablets are low in calories and contain no free sugar.

Patent CA-2430272-A1 (CA)
Inventor: MAYER YARON
IPC: H04N/
Filed: 2003-06-02
Abstract: One of the most frustrating things when recording for example songs from the radio is that many times by the time the user decides that he/she would like to record for example some song, the beginning of the song is already lost. Or the user might zap between radio stations and tune into the station after the song has already started or for example after the beginning of an interesting conversation or message or News item and is frustrated that he missed the beginning of it. Similarly, for example while zapping through cable TV stations, a user might find for example a fascinating scientific program or a fascinating report and regret that he/she had not seen or recorded it from the start for later reference. The idea of retroactive recording and/or replay has existed already since 1990 and there are a number of patents about it, but they do not deal with the problem of enabling retroactive recording and/or replay also when the user is zapping between channels for example on radio or on TV. The present invention describes an improved system and method for automatic time-shifted retroactive recording or replay, that applies retroactive recording and/or replay also to a situation of switching between channels. Additional improvements and possible implementations are also shown.

Abstract: A blow-molded plastic bottle body (10) for use in containing hot-filled beverages. The bottle body (10) has a dome (12) with various interactive functional zones. For example, some of the zones are primarily responsible for accommodating vacuum absorption, while other zones are primarily intended to rigidify the container such as by providing column strength to improve container top loading capability. Although each zone may have a primary funciton, each zone also aids adjacent zones in providing their functions.  Thus, the entire dome (12), and not merely selected locations, reacts in a progressive manner to the forces generated by the hot-fill process on the bottle body (10). Preferably, the bottle body (10) is slender and capable of readily being gripped by a single hand, and preferably the flex panels (28) in the dome (12) accommodate at least 90 % of the total vacuum absorption required by the bottle (10).

Abstract: The present invention provides an apparatus, system and method which enables a determination of pressure on a surface which is coated with a pressure sensitive paint which, when flashed with light, exhibits return light with a decay time constant as a function of surface pressure. The system controls a light source which is adapted to emit a train of light pulses directed at the coated surface and controls a camera adapted to collect light level data from the surface. Further, a synchronizer is used to provide timing and control of the light source and the camera in which the synchronizer enables the light source and subsequently enables the camera to collect light level data in first and second gate periods. A decay time constant is determined from the data collected in the first gate period and the second gate period.

IPC: G06K7/00
Filed: 2002-02-25
Abstract: In order to operate non-contact identification media RF-IM in a system having contact applications C-App for contact cards C-IM, an initialized converter module C-RF is interconnected as a write/read station. Said converter module executes, on the one hand, a non-contact communication K-RF with initialized non-contact identification media RF-IM and, on the other hand, a contact communication K-C on a contact card interface S to a host computer H or to an application computer App-uP for communicating with a contact application C-App of the system. The converter module translates the non-contact communication K-RF with regard to communication rules and information I-RF into a contact communication K-C with contact information I-C and vice versa. This permits a particularly simple and rational introduction of non-contact identification media RF-IM into existing contact card systems and installations.
