Abstract: On décrit un guide interactif de programmes de télévision qui permet de déterminer des valeurs d'entrée utilisateur pour des catégories démographiques. Le guide inclut un équipement télévisuel de l'utilisateur (44) comprenant un récepteur pour recevoir des informations relatives au guide interactif des programmes de télévision, un récepteur d'entrée utilisateur (62) pour recevoir une entrée utilisateur à partir d'une interface utilisateur, telle qu'une télécommande (54), un microprocesseur qui utilise l'entrée utilisateur reçue pour déterminer des valeurs d'entrée utilisateur pour des catégories démographiques, et une mémoire pour stocker les valeurs d'entrée utilisateur déterminées. Dans une forme de réalisation typique mettant en oeuvre des annonces publicitaires destinées à un utilisateur d'un guide interactif de programmes de télévision, le récepteur reçoit également des annonces publicitaires lorsque celles-ci comportent des valeurs préétablies pour des catégories démographiques spécifiées. L'équipement télévisuel de l'utilisateur, utilisant de préférence un microprocesseur, compare les valeurs préétablies pour les catégories démographiques spécifiées associées aux annonces publicitaires avec des valeurs de catégories démographiques correspondantes stockées en mémoire pour déterminer celles des annonces qui doivent être présentées. Les annonces choisies sur la base de cette comparaison sont ensuite présentées.

Patent CA-2338367-A1 (CA)
Inventor: HIPPER AUGUST
IPC: E04F15/02
Filed: 2000-04-25
Abstract: What is disclosed is a joint for two flat structural members, in particular floor panels. wherein a groove and tongue joint is provided functionally separate from locking. This locking is effected by a twistlock of a structural member, said twistlock being spaced apart from the groove and tongue joint and engaging with a correspondingly formed engaging element of the other structural member. The locking is preferably formed both at the longitudinal edges and at the front edges of a rectangular structural member, for instance of a floor panel. The locking allows for a joint of the floor panels in flat position, i.e. without twisting.

Title: Method and apparatus for implementing international wireless roaming
Inventor: KOSTER KARL H
IPC: H04W8/12
Filed: 1999-07-16
Abstract: A method and apparatus for implementing international wireless roaming allows an international "roamer" to enter a visited system in a foreign country and originate calls. Upon entering the visited region, the roamer's mobile station initiates a registration request containing the mobile station's mobile identification number to the mobile switching center in the visited region.  The mobile switching center initiates a message to an appropriate home location register. The home location register compares the mobile station's mobile identification number to a set of stored values. If an agreement is in place between the home location register provider and the roamer's home service provider, the home location register will return an appropriately formatted North American Numbering Plan mobile directory number to the mobile switching center. When the roamer initiates a call, the mobile switching center uses the mobile directory number in signaling call related information, specifically in populating parameters such as the Calling Party Number.  Recognizing a NANP-formatted number, the public switch telephone network will process the call as normal.

Abstract: An inlet (11a) and an exit (11b) are formed at opposite ends of a chamber (11), and transporting means (12) is moved into the chamber from the inlet toward the outlet. The transporting means is constituted to transport a plurality of works (19) at predetermined intervals.      Disposed within the chamber is a pair of electrode plates (13, 14) along the longitudinal direction of the transporting means and at predetermined distances from the works, respectively so as to interpose the works between the pair of electrode plates. Smoke to be adhered to and infiltrated into works is constitutionally generated by smoke generating means (16) and introduced into the chamber.      Applied between the pair of electrode plates is a DC voltage or AC voltage of 7 kV to 15 kV by a high voltage generating circuit, and works are grounded.      This reduces the amount of electric power consumption, downsizes the apparatus, and renders the smoke to uniformly adheres to and infiltrates into works, to thereby improve the quality of smoked foods.

IPC: G06F9/44
Filed: 1999-08-26
Abstract: Tasks associated with an add-on software program can be seamlessly incorporated into core software tasks. A directory associated with the add-on is interrogated for similar tasks when the corresponding task is actuated in the core software program. The directory names are copied over into an array associated with the core software program and a link is created between those names in the array and the directory from which they were taken. Thus, a drop-down menu may be implemented in a task or navigation bar in the core software program which allows the corresponding tasks in the add-on to be seamlessly incorporated into the operation of the core software.

Title: Method of modifying harmonic content of a complex waveform
Inventor: SMITH PAUL REED
IPC: G10L25/90
Filed: 1999-10-29
Abstract: A method of manipulating a complex waveform by considering the harmonic and partial frequencies as moving targets over time in both amplitude and frequency and adjusting the moving targets by moving modifiers in both amplitude and frequency. The manipulation of harmonic frequencies and the synthesis of harmonic frequencies are based on the harmonic rank. The modifiers move with the movement of the frequencies based on rank. Harmonic transformation modifies, by rank, the waveform from one source to a waveform of a second or target source. Harmonics and other partials accentuation identifies each of the frequencies and its relationship to adjacent frequencies as well as fixed or moving thresholds and make the appropriate adjustment. Interpolation is also disclosed as well as models which imitate natural harmonics.

Patent CA-2352415-A1 (CA)
Inventor: BOYLE PATRICK JOSEPH
IPC: H04M3/00
Filed: 2001-07-04
Abstract: The present invention provides a method for limiting the number of simultaneous call forwarding attempts for a mobile unit. A call is made for a mobile unit. The call request is sent to the MSC associated with the mobile unit.      When the mobile unit is not currently active at the MSC, the MSC sends a location request to an SCP. The SCP responds with a return message that includes a temporary location directory number (TLDN) and an indicator. The MSC checks the current number of simultaneous call forwarding attempts being made for the mobile unit. If the current number of simultaneous call forwarding attempts exceeds a threshold, the MSC does not forward the call. If the number of simultaneous attempts does not exceed a threshold, the MSC forwards the call to the mobile unit by sending it to the TLDN.
