Title: Data reproduction apparatus and method for reproducing a data stream using discontinuities of time clocks
Inventor: KATO MOTOKI
IPC: H04N21/235
Filed: 2001-11-20
Abstract: The present invention relates to a data recording apparatus capable of properly managing contents of data and reproduction information even if a portion of the data is deleted. If a portion of Clip is deleted so that an ATC-sequence becomes discontinuous, the value of offset_STC_id for an STC-sequence at the beginning of the ATC-sequence is set so that the value of stc_id of each STC-sequence following the ATC discontinuity does not change. stc_id of an STC-sequence is an ID for identifying the STC-sequence. The present invention can be applied to an operation to record an AV stream onto an optical disk.

Inventor: KEENAN TIMOTHY
IPC: A61M31/00
Filed: 2008-11-26
Abstract: A patient controlled analgesia device generally includes: a patient controlled analgesia pump and a biometric authentication system. The biometric authentication system generally includes a biometric pump controller coupled to the patient controlled analgesia pump that activates the patient controlled analgesia pump to deliver analgesia and a biometric switch adapted to receive a biometric input and operably coupled to the biometric pump controller to activate the biometric pump controller. A biometric authentication processor in the biometric pump controller activates the patient controlled analgesia pump to deliver analgesia only upon authenticating the biometric input received at the biometric switch. Optionally, the biometric pump controller also includes a dosing processor that limits delivery of analgesia according to a prescription.

Abstract: Selon le centre de recherche de la Croix-Rouge, chaque année au Canada, une moyenne de 23 personnes se noient en motoneige. Au Québec, la noyade est l'une des principales causes de décès en motoneige, en 2009, 7 des 22 décès en motoneige ont été causé par la noyade. Le grand danger est que l'épaisseur de la glace peut se modifier en moins de quelques heures à cause des conditions météorologiques changeantes. J'ai fait des recherches pour trouver si un dispositif existait pour sauver de la noyade les motoneigistes. A ma grande surprise je n'ai trouvé aucun dispositif. Il existe par contre des habits munis de dispositif de flottaison. Les points faibles de ces vêtements c'est que rien ne garantit que le motoneigiste le porte et, en cas d'immersion, ces habits ne protègent pas de l'hypothermie ni ne garantit que le motoneigiste puisse sortir de l'eau. J'ai trouvé une façon simple de garantir la survie et même de sauver de l'hypothermie le motoneigiste en cas d'immersion de sa motoneige.

Filed: 2004-12-07
Abstract: A plurality of page message requests for a plurality of mobile devices operating in a wireless communication network are received. One or more paging slots assigned to the mobile devices are identified for transmitting a plurality of page messages in response to these requests. To permit higher priority page messages to be transmitted within the paging slots, a page message from a mobile device associated with a tolerable delay indication is not transmitted. The wireless network subsequently causes the page message for the mobile device having the tolerable delay indication to be transmitted within one or more subsequent paging slots within a tolerable delay period corresponding to the tolerable delay indication. The mobile device may transmit the tolerable delay indication to the wireless network in response to identifying a predetermined condition, for example, identifying use of a high capacity power source.

Patent CA-2762111-A1 (CA)
Title: System for encrypting and decrypting a plaintext message with authentication
Inventor: SMITH ERIC MYRON
IPC: H04L9/32
Filed: 2010-05-17
Abstract: The described system and method provide for an encryption and authentication technique that achieves enhanced integrity verification through assured error-propagation using a multistage sequence of pseudorandom permutations. The method generates intermediate data-dependent cryptographic variables at each stage, which are systematically combined into feedback loops. The encryption technique also generates an authentication tag with minimal post processing that is the size of the state. The size of the state is dependent on the number of pseudorandom permutations and the size of the LFSR. The authentication tag provides a unique mapping to the plaintext for any number of plaintext blocks that is less than or equal the size of the state. In addition to being a stand alone encryption algorithm, the disclosed technique is applicable to any mode that uses pseudorandom permutations such as, key dependent lookup tables, S-Boxes, and block ciphers such as RC5, TEA, and AES.

Abstract: A clampless fitting for one or more plastic pipes. The fitting has at least one section extending along an axis with a sealing portion and pipe gripping portion adjacent one another on the outer surface of the section. The pipe gripping portion includes a recess extending about the axis of the fitting section with a pipe gripping ring removably received in it and extending substantially about the axis. The ring is substantially C-shaped about the axis and has a plurality of pairs of first and second end segments spaced from each other along the axis and respectively joined by a central pivot segment. In operation, the fitting section is inserted in a first direction into the open end of the plastic pipe to a first location relative to the pipe in which both the sealing and pipe gripping portions are received in the pipe. The second end segment of the ring has a pipe piercing, tip section that is supported above the inner surface of the pipe as the pipe passes over the fitting section to the first relative location. Movement of the fitting section and pipe in an opposite direction away from each other will then cause the upstanding tip sections of the second end segments to pierce the inner surface of the pipe and move into the pipe wall and pivot the first and second end segments of the ring to abut one another to secure the fitting section and pipe in place.
