Patent CA-2533521-A1 (CA)
Inventor: LEWIS NOLAND
IPC: H04R1/00
Filed: 2006-01-20
Abstract: A sound isolation cap for use with a sound level meter. The cap has a bore in which a plug snugly fits. The plug, in the open position, allows air to travel between the exterior of the cap and the cap's interior cavity. In the closed position, the plug prevents air from traveling between the exterior of the cap and the interior cavity. Air may travel between the interior cavity and the exterior of the cap by way of two passages. One passage connects the interior cavity with the bore while the other passage connects the bore with the exterior of the cap. When in use, the microphone of the sound level meter is inserted into the interior cavity.

Title: Snow sled with dual-mode braking system
Inventor: STEVENS BOB F
IPC: B62B17/08
Filed: 2006-02-08
Abstract: Disclosed is a snow sled with brake pedals that can be actuated operated either independently or cooperatively by foot pressure or by manual cable-brake control levers, to press the brake shoes into the snow surface over which the sled is traveling, thereby braking the sled. The brake pedals are pivotably suspended from the sled frame so that the rider's feet can rest upon them. The lower portions of the pedals form brake shoes extending downward and rearward from the foot rest portions of the pedals, such that the brake shoes can be pressed into the snow surface by applying foot pressure to the pedals. Alternatively, the brake pedals can be actuated by a bicycle-style cable-brake lever. Cable-biasing means is provided to keep the brake cable taut when the brake pedals have been partially actuated by foot pressure, so that the cable-brake system remains operatively effective at all times. The brake pedals may be interconnected by a bridging structure such that both pedals will tend to move toward the engaged position even when foot pressure is applied to only one pedal. Alternatively, the brake pedals may be independently operable, with separate cable-brake control systems.

Abstract: A system and method are provided for performing a cashless gaming ticket redemption transaction for a customer in a casino environment. The system includes a gaming machine, such as a slot machine, that the customer plays.  Rather than issuing cash to the customer, the gaming machine issues a redemption ticket with a unique identifier to the customer. The unique identifier and the amount of the customer's winnings accrued on the gaming machine are stored and associated on a redemption ticket database. When the customer wishes to redeem the winnings, the redemption ticket is introduced to a multi-function ATM. To perform the ticket redemption transaction, the ATM is adapted to electronically accept the redemption ticket and read the unique identifier. The ATM then electronically communicates with the redemption database to retrieve the predetermined dollar value associated with the unique identifier. Finally, the ATM transfers to the customer an award equal to the predetermined dollar value in cash or credit.

Title: Transformers
Inventor: LEWIS ERIC ANTHONY
IPC: H02J3/18
Filed: 2005-08-25
Abstract: The invention provides a multi-transformer unit (20) for converting an input AC voltage at a first voltage level HV to a net output AC voltage at a second voltage level LV. The multi-transformer unit (20) can be used in place of a conventional transformer or an AC machine and is designed to suppress the transfer of harmonics between the input and output AC voltages. The unit comprises at least two phase-shifting transformers (22, 24), each transformer being operative to provide a phase shift relative to the first voltage level HV. On the primary side of the unit the transformers (22, 24) are arranged for independent connection to the first voltage level, whereas on the secondary side of the unit the transformers are linked such that voltage vectors on the secondary side of the unit are added together to at least partially cancel the harmonic pollution and give the net output AC voltage. Moreover, the phase shift of the phase-shifting transformers may be selected to completely or substantially add into the net AC output voltage of the multi-transformer unit (20) the fundamental voltage/frequency applied to its input AC voltage.

Abstract: La présente porte sur un système et une méthode de multiplexage par répartition orthogonale de la fréquence (MROF) utilisant la manipulation par changement d'amplitude (ASK) pour une modulation ide sous-porteuse. Parce que l'ASK est utilisée, le signal de chaque symbole en domaine temporel est conjugué-symétrique. De plus, parmi les nombres discrets de chaque symbole, deux d'entre eux sont toujours réels. Ces propriétés sont utilisées de façon que seulement la moitié des nombres de chaque séquence de symbole est transmise. Le signal dans la bande de base généré peut être un signal complexe ou réel. En conséquence, l'efficacité de la largeur de bande de l'ASK-OFDM dérivée est la même que celle de la QAM-OFDM.

Abstract: The present invention relates to the use of copper ions to achieve enhanced retention of a therapeutic agent within a liposome. The invention may be employed to more effectively deliver a liposomally encapsulated therapeutic agent to a target site in vitro and in vivo for anti-cancer or other therapy.  The liposome may comprise an interior buffer solution containing the therapeutic agent, the solution having a pH less than 6.5 and most preferably approximating pH 3.5. At least some of the copper ions are retained within the interior solution. In a particular embodiment the therapeutic agent may be a chemotherapeutic drug, such as irinotecan. The invention may also comprise an ionophore to facilitate loading of drug into the liposome. In one particular embodiment the combination of the ionophore A23187 and encapsulated divalent copper (Cu2+) resulted in an irinotecan formulation that exhibited surprisingly improved drug retention attributes.
