Patent CA-2078089-A1 (CA)
Inventor: KOCINSKI RICHARD J
IPC: B05B17/06
Filed: 1992-09-11
Abstract: An improved aerosol chamber for an ultrasonic nebulizer which prevents relatively large medicament droplets from being inhaled by a patient.  The chamber has a housing formed from a polycarbonate resin and is generally cylindrically shaped with a spherical top surface.  The chamber includes an air inlet formed in the top surface and an aerosol outlet formed in a side surface. A centrally located mist tube extends coaxial from the air intake downwardly past the aerosol outlet.  A longitudinally extending slot is formed in the mist tube facing the side surface of the housing diametrically opposite the outlet.  The slot extends from a lower edge of the tube upwardly toward the air intake.  A geyser baffle is disposed at an angle within the mist tube above the slot to deflect larger droplets away from the slot.  The baffle includes an upper edge spaced from an adjacent inner surface of the mist tube to define a relatively small gap to allow inlet air to flow through the mist tube.  The air flow entrains nebulized medicament droplets, flows through the slot and through an annular space between the mist tube and the housing to the outlet.  The annular space creates a cyclone effect which causes larger droplets to condense on the interior walls of the housing.

Abstract: PHN 13864                                        30.03.1992 ABSTRACT:         Charge-coupled device.     The invention relates to a charge-coupled device which has two or more parallel channels provided with a demultiplexer by which a series of consecutive signals is distributed over the parallel channels.  For each signal, a given number of charge packages is formed, corresponding in size to the input signal, of which only one is stored in the relevant channel while the remaining charge packages are drained off. This method of demultiplexing imposes no or at least substantially no speed limitations on the device, which as a result is particularly suitable as a memory or delay line for very high frequency signal, for example, of 1 GHz.  In a particular embodiment, the charge-coupled device is of the buried channel type with an npn (or pnp) structure in which the charge packages are drained off through the substrate.   Fig. 7 .

Inventor: MOLNAR RICHARD J
IPC: G06F3/05
Filed: 1993-10-08
Abstract: A device which  is  a combination of  a method and apparatus and a filter,  such as but not limited to,  a conventional  lag  filter  for  digitally  processing  and filtering signals used in industrial control applications.        The method and apparatus provides a factor which is used by the filter to process the digital signal at the input to the device.  The method determines if the change in the input signal is either due to noise or a valid signal change.          Information which gives a past analysis of the trend in direction of the signal at the input to the device is used in the method.   The trend information includes a factor representative of the past history of the trend.  The method uses the most  recent  trend  indicator  to determine to a reasonable degree of confidence if the signal currently at the input to the device is or is not characteristic of noise.  If the signal at the input is not believed to be characteristic of noise, then the method adjusts the trend indicator by a tracking credit.  The tracking credit is, in effect, a further degree of confidence that change in the input signal is not characteristic of noise.   The method minimizes the tradeoff between valid signal response time and noise rejection associated with the prior art filters.

The memory controller utilizes different speed memory devices at each memory devices optimal speed.  The functions are performed by a plurality of simple, interdependent state machines, each responsible for one small portion of the overall operation.  As each state machine reaches has completed its function, it notifies a related state machine that it can now proceed and proceeds to wait for its next start or proceed indication.  The next state machine operates in a similar fashion.  The state machines responsible for the earlier portions of a cycle have started their tasks on the next cycle before the state machines responsible for the later portions of the cycle have completed their tasks.  The memory controller is logically organized as three main blocks, a front end block, a memory block and a host block, each being responsible for interactions with its related bus and components and interacting with the various other blocks for handshaking. The memory system includes a single chip which provides all of the address and control signals to a memory device so that a clock cycle can be saved because of reduced skew of the signals.
