Patent CA-2305272-A1 (CA)
Inventor: KING SUSAN MELTON
IPC: A47D13/08
Filed: 1998-09-10
Abstract: An infant sleeper is provided that has raised wall portions (7, 9) positioned to approximately correspond to the center of mass of the infant so as to provide maximum retention support and security to the infant. The raised wall portions (7, 9), in combination with a horizontal surface (11) on which the infant rests, secures the infant to the bed. The head can be inclined at an angle so that the head of the infant can be kept slightly above its foot. The portion of the bed that lacks the raised wall portion provides as little obstruction as possible to the head of the infant so as to reduce potential feelings of claustrophobia as well as possible obstructions to breathing such as from blankets. Hence, the present invention combines a secure place for an infant to sleep with a sense of openness and freedom. It is believed that this position allows the infant to rest in a more correct anatomical position so as to ameliorate potential respiratory conditions and especially sudden infant death syndrome (SIDS).

Patent CA-2305589-A1 (CA)
Title: System and method for providing restrictions on mobile-originated calls
Inventor: BOLTZ DAVID
IPC: H04M1/66
Filed: 1998-09-30
Abstract: A cellular telephony network includes a supplementary service (SS) database in an intelligence network (IN) node. The SS database stores subscriber record which includes call barring data such as screening lists of specific numbers or countries and call barring options that indicate the treatment of the call barring data. The SS database may be located in an IN node connected to a mobile service center/visitor location register in a cellular telephony network or a signaling database point in a signaling network connected to the cellular telephony network or in the home location register of the cellular telephony network. At call origination, the MSC/VLR transmits the requested called number and MSISDN of the mobile subscriber to the SS database. The IN  node compares the requested called number to the subscriber record associated with the MSISDN of the mobile subscriber and transmits a message to the MSC/VLR indicating whether the call is barred. In an alternate embodiment, a subscriber record is stored on a subscriber identity module (SIM) in a mobile station. The SIM stores a subscriber record of the mobile subscriber associated with the SIM. At call origination, the mobile station reads the subscriber record stored in the SIM and compares the requested outgoing call to the call barring options. If the subscriber record indicates that the call is barred, the mobile station displays a call barred message to the mobile subscriber.

Title: The formation of indicia in the base of a blister pack for transference to a body cast therein
Inventor: HEATH KENNETH
IPC: B29L9/00
Filed: 1999-08-06
Abstract: The invention herein relates to a method and apparatus for forming (or cold-forming) an embossed blister from a laminated film wherein an indicia is formed on the base of the blister. In particular, the invention involves a single pass process of combining the formation of a blister and the formation of an indicia (embossing) on the blister, wherein the blister-forming pin contains a face with an indicia and is adapted to controllably stretch the laminated film during blister formation to minimize stretching of the film at the base of the blister. The invention is particularly useful in manufacturing processes which involve the formation of blisters having laminated films which contain a metal foil and polymer layer, wherein improved control in the stretching of the laminate during blister formation is desirable.
