Abstract: An aerosol dispensing inhaler training device for determining whether a user is properly operating an aerosol dispensing device. The training device includes an aerosol dispensing device having a container with a valve stem extending longitudinally therefrom and movable between a closed position and an open position. The container dispenses a portion of the contents within the container when the valve stem is moved to the open position. The aerosol dispensing device includes a housing adapted to support the container reciprocally moveable within the housing along a longitudinal axis from a first position, the housing comprising a well adapted to receive the valve stem and an exhaust port comprising one end in fluid communication with the well and a second end in fluid communication with the ambient atmosphere, wherein the portion of the contents within the container is dispensed from the first end of the exhaust port to the second end of the exhaust port when the housing moves to an actuation position where the valve stem is actuated so that a portion of the contents within the container is dispensed through the second end of the exhaust port when the valve stem is moved to the open position. An actuation sensor generates a signal that indicates when the housing is moved to the actuation position and the valve stem is actuated. A shake sensor determines whether the contents within the container have been properly agitated for consumption by a user.

Patent CA-2266142-A1 (CA)
Inventor: WILLIAMS JAMES F
IPC: F16K31/126
Filed: 1999-03-19
Abstract: A valve system for starting/restarting an oscillating controller of the type that uses a source of pressurized gas to provide controlled pulses of the pressurized gas to a pump, such as a chemical injector pump. The start/restart valve includes a valve element that is closed by a valve spring when the pressure of the pressurized gas source drops below a predetermined minimum and is opened upon the pressure increasing to a second predetermined pressure higher than the predetermined minimum pressure to thereby provide a higher pressure for starting or restarting the oscillating movement of the controller. The start/restart valve includes a detent mechanism for maintaining the valve element in either the open or closed position until the gas pressure reaches the appropriate pressure level for switching to the opposite position. The opening of the valve element may be caused by the gas pressure being applied directly to the valve element or indirectly through a diaphragm in alternate embodiments. In still another embodiment, the start/restart valve system includes a solenoid valve that is operated in response to a pressure sensor that determines the pressures at which a solenoid valve is opened and closed electrically.

Title: Radiocommunication systems and terminals with increased payload bandwidth
Inventor: RAITH ALEX KRISTER
IPC: H04B7/26
Filed: 1997-10-10
Abstract: Variances in bandwidth used by a radiocommunication connection are adapted to by changing the type of information being transmitted. For example, in a TDMA environment, a first downlink time slot associated with a double- or triple-rate connection may have a first format, while a second time slot associated with the same connection may have a second format different from the first format. Additional bits in the second (or third) time slot can be used to carry payload information which is not required to be transmitted at greater than full-rate.      Moreover, FACCH information need only be transmitted in the master channel.

Title: Method and means for synthesis-based simulation of chemicals having biological functions
Inventor: HUSE WILLIAM D
IPC: G06F19/00
Filed: 1997-11-25
Abstract: Using a programmed, general purpose digital computer, biological effectiveness of synthesized chemicals is simulated. The synthesized chemicals are modelled by data structures that embody a relationship between chemicals of which the product chemicals are composed and reaction sequences under which the chemicals are combined to produce the synthesized chemicals. The modelling includes models in the form of data structures that represent experimentally performed or hypothetically specified synthesis procedures. The models are subjected to a simulation function that predicts feasibility of a specified synthesis procedure and the biological function of chemicals produced by the specified synthesis procedure. The simulation function operates on the models to produce simulation results. One or more product chemicals are synthesized according to the hypothetically specified synthesis procedures and are assayed to produce actual assay results. The simulated results are compared to the actual assay results while referencing a tolerance limit. The simulation function is changed until the comparison has a predetermined acceptability relationship with the tolerance limit.
