Title: Treat dispenser for animals and method
Inventor: MARKHAM JOSEPH P
IPC: A01K29/00
Filed: 2010-10-04
Abstract: A dispenser device is provided for use by an animal to selectively dispense treats from the device. The device includes a body having an interior opening to receive treats, and an opening is formed in the body to allow dispensing of the treats. A base of the device includes a weighted material therein causing the device to reside in a normally upright position. Contact by the animal causes the device to tip, thereby allowing treats to fall through the opening in the body. Changing the amount and type of material used for the weighted material changes the characteristics of how the device moves when contacted by the animal that in turn, changes the rate and amount of treats that are dispensed.

Abstract: A method and a device for reconfiguration in a wireless system utilizing flexible layer one (FLO). In proposed solution one TFC (Transport Format Combination) is selected and reserved (504) exclusively for signalling use. The TFC may contain only one active transport channel and always utilize the same CRC and transport block size in order to unambiguously define the proper settings for signalling. Considering uplink transmission in a wireless system and special case of TFCI (Transport Format Combination Identifier) size change due to the TFCS (Transport Format Combination Set) reconfiguration that also generates a need to switch to a new dedicated basic physical subchannel (DBPSCH); whenever the network notices that the mobile station does not switch to the new DBPSCH (518), it concludes that the TFCS reconfiguration message sent was lost and stays with the existing configuration (520). Otherwise the new configuration is taken into use (514).

Title: Hockey stick with a curved shaft
Inventor: CROSSLEY LANCE D
IPC: A63B59/70
Filed: 2012-12-11
Abstract: An improved ice hockey stick where the shaft portion of the stick is concavely curved along the entire front face of the shaft and convexly curved along the entire back face of the shaft. The front face of the shaft is a concave surface with no points of inflection, and the back face of the shaft is a convex surface with no points of inflection. This design differs from an angled shaft in that no portion along the shaft length is straight.  The degree of concavity (or convexity) may vary depending on a hockey player's strength, and on the material used to construct the shaft. When a hockey player takes a shot the entire stick shaft becomes straight by the moment of impact with the puck and/or during contact with the puck thus maximizing the force applied to the puck.
