  • Publication number: 20240139441
    Abstract: A system may include a mobile application residing on an external device and an inhalation device. The inhalation device may include a mouthpiece, a mouthpiece cover, medicament, and an electronics module comprising a processor. The inhalation device may be configured to both prepare a dose of medicament for delivery to a user and cause the processor to transition between power states when the mouthpiece cover is moved from a closed position to an open position to expose the mouthpiece. The electronics module or the mobile application may be configured to generate usage events based on usage of the inhalation device by the user. The electronics module may also include a pressure sensor, and the electronics module or the mobile application may be configured to determine whether a usage event is a good inhalation event, a fair inhalation event, or a no inhalation event based on feedback from the pressure sensor.

  • Patent number: 10515493
    Abstract: Methods, systems, and techniques for tracking and pictorially displaying locations of tracked individuals involve retrieving a location of the tracked individual and pictorially representing the location of the tracked individual on a display. The location can be acquired using a credentials acquisition device to read credentials issued to the tracked individuals. Pictorially representing the location on a display may involve showing one or both of the location and number of the tracked individuals on a map.

  • Patent number: 5261139
    Abstract: A raised powered baseboard brush apparatus (10) for use on top of a conventional corner sweeper attachment (100) for a powered floor sweeper (200) for engaging a rotating elevated baseboard brush member (26) into contact with the top portion of a baseboard (50) disposed parallel to the line of travel of the powered floor sweeper (200).

  • Patent number: 4857765
    Abstract: An integrated semiconductor VLSI chip design that increases the number of driver circuits, or groups of driver circuits, that can be simultaneously switched. Timed driver gating signals, or driver enable signals, are used, in conjunction with physical grouping of driver circuits on the chip, to isolate switching drivers from quiet drivers. This construction and arrangement minimizes detrimental effects usually caused by noise that is generated when driver circuits switch.

  • Patent number: 4774712
    Abstract: A memory device for storing data and providing address and data line error detection is disclosed. A memory holds two copies of data, each copy of data having opposite parity dependent on its address. An address sequencer provides addresses to the memory. The addresses are modified to select the copy of data in the memory having a predetermined first parity. A parity checker checks the parity of data provided by the memory and provides an error indication if the parity is incorrect, said error indication being indicative of address and data line errors and memory cell errors. When an error is indicated by an error latch, the error causes a retry of the memory in the location where the desired data is stored with parity opposite the first parity.

  • Patent number: 4698760
    Abstract: A method of optimizing signal timing delays and power consumption through multi-path LSI circuits constructed from a plurality of circuit blocks, each circuit block having associated therewith a plurality of power levels which are selectable to control the timing delays through the circuit block, wherein the method steps include the formation of a power-performance derivative for each circuit block, identifying therefrom the relative contribution to signal delay of the circuit block in the entire multi-path configuration, and selecting the optimum power level for an overall multi-path minimum signal delay condition, through a process of iterative calculation of timing delays through individual circuit blocks and multi-path timing analysis.
