Title: System and method for exchanging encryption keys between a mobile device and a peripheral device
Inventor: BROWN MICHAEL S
IPC: H04L9/28
Filed: 2006-05-12
Abstract: Embodiments of a system and method for providing additional security for data being transmitted across a wireless connection that has been established using a known wireless protocol (e.g. Bluetooth) are described. An encryption key is exchanged between a computing device (e.g. a mobile device) and a wireless peripheral device (e.g. a keyboard, a printer). In exemplary embodiments, the encryption key is generated at one of the two devices. Data associated with the encryption key is output at the one device, which can be input by the user at the other device. The encryption key is then recovered at the other device from the input, thereby completing the key exchange. The encryption key can then be used to encrypt and decrypt data transmitted over the established wireless connection, providing additional security.

Title: Improvements in or relating to the defeat of the copy protection of optical discs
Inventor: HEYLEN RICHARD A A
IPC: G11B20/00
Filed: 2005-02-04
Abstract: DVDs can be copy protected by incorporating regions which contain unreadable or subversive data within the data area (42). For example, such a region may be configured as a cell of a video object (VOB) (50) within a VOB file (51).  Access to the region of subversive data is prevented during normal playback, for example, by ensuring that there are no pointers leading to the subversive region. To defeat such a copy protection method, the content on the copy protected optical disc is accessed by utilising the navigation provided for normal playback of the disc. Thus, the subversive regions are navigated around during copying of the disc. The accessed content is stored in a corresponding data area and, where subversive regions are identified, arbitrary data is incorporated within regions of the copy data area which correspond to regions of unreadable or subversive data in the original data area.
Patent CA-2555022-A1 (CA)
Inventor: CHANG TSU LING
IPC: B65H16/10
Filed: 2005-01-31
Abstract: A system and apparatus for automatically dispensing a paper product mounted on a gravity-assisted holder through a dispenser. The apparatus includes an electric motor, a main product roller for automatically rolling a predetermined amount of the paper product from the holder, exit guide rollers for guiding the paper product through a front cover of the dispenser, and a series of interconnected gears that are driven by the electric motor to activate the main product roller and exit guide roller and operate both the main roller and exit roller at the same speed. Operating the rollers at the same speed prevents paper or tissue jamming inside the dispenser. The system monitors usage of each paper product dispenser with each dispenser having a microprocessor controller for determining a corresponding paper product status for the dispenser. Each paper product dispenser communicates with a master network device preferably mounted on a ceiling plane. Paper product status messages are transmitted between each dispenser and master network device unit using a standard data communications protocol. The master network device communicates the paper product status for each individual dispenser to an independent building automation and control network. A central control console that is interoperable with the building automation and control network monitors the status of each paper product dispenser through signals communicated from a master receiver/transmitter unit to the central control console.

Patent CA-2559991-A1 (CA)
Inventor: LOCKE ANDY
IPC: B23C5/12
Filed: 2006-09-14
Abstract: A rotary cutting tool fed along its axis of rotation is used for cutting processes in which teeth of the tool do not continuously engage a workpiece, such as forming a cope. A cylindrical body of the tool is fluteless in order to keep the tool's cutting swath to a minimum thickness and thus reduce the cutting forces and heat generation from those of conventional annular metal cutters.  Circumferential spacing of teeth about an annular end face of the body acts to contain material removed from the workpiece until reaching a portion of the tool's rotational path in which the workpiece is not engaged, at which point the material is freed from the tool to prevent jamming. An outer surface of the cylindrical body is continuous over a substantial majority of its length in order to ensure adequate tool strength.

Title: Methods and apparatus for delivering aerosolized medications
Inventor: SUDHALKAR ATUL M
IPC: A61M11/00
Filed: 1998-07-14
Abstract: A metered dose inhaler (10) for use with a pressurized aerosol canister (18) includes a housing (12) defining a conduit (16) with a mouthpiece (56), and an actuator (26) with a nozzle discharge orifice (30) arranged to discharge aerosol into the conduit. An air tube (34) is arranged within the conduit with an inlet (38) of the air tube formed in the conduit wall (74) and an outlet (36) of the air tube in opposing relationship with the nozzle orifice. Inhalation through the mouthpiece causes air to be drawn into the inlet and flow out of the outlet of the air tube to form an air jet which impinges on an oppositely moving aerosol plume from the orifice. Auxiliary air inlets (46) in the closed end (24) of the conduit provide a boundary layer flow along the inner wall (44) of the conduit. Vortex generators (54) on the inner wall of the conduit add vorticity and turbulence to the boundary layer flow. Automatic actuation of the canister responsive to the patient's inhalation is achieved by a canister trigger (154) connected to a movable piston assembly (132) forming a wall of a variable-volume chamber (162) in fluid communication with a venturi (184) in the air tube. Air drawn through the venturi by the user's breath causes evacuation of air from the chamber, thereby moving the piston assembly and trigger to cause actuation of the canister.

Title: Self-contained emergency eye wash station
Inventor: RIBACK RICHARD J
IPC: A61H35/02
Filed: 1996-05-22
Abstract: A self-contained emergency eye wash station for dispensing eye wash fluid contained in a flexible container comprises a housing, a reservoir, and a platen. The housing supports the flexible container and supports a nozzle in fluid communication with the flexible container. The nozzle dispenses the eye wash fluid from the flexible container. The housing includes a drain capturing the eye wash fluid dispensed from the nozzle. The reservoir collects the eye wash fluid captured by the drain, and the reservoir is slidably mounted to the housing. The platen is connected to the reservoir. The platen is slidably movable relative to the housing and is located immediately above the flexible container. The platen presses downward on the flexible container with a downward force proportional to a weight of the eye wash fluid collected in the reservoir. The transfer of the weight of the eye wash fluid collected in the reservoir to the platen maintains a constant flow of eye wash fluid dispensed from the nozzle.
