Abstract: Improvements in an access point through a wall or ceiling for gaining access through the wall or ceiling using only one side of the wall or ceiling. After cutting a home the housing or frame for can then be pushed into the opening for installation and the installer can compress one-way retaining arms to secure the frame without requiring the use of any additional tools or requiring access to the back of the wall, ceiling or floor. The frame has locating key(s) ensures that the cover or electronics is installed in the preferred rotational orientation. One or plurality of locating keys that ensures the internal electronics can be installed in one or more than one orientation to minimize confusion regarding an acceptable orientation. The rotation positions can also be used to ensure that a logo or internal feature or cover is properly oriented.

Abstract: A computer memory apparatus is provided having a plurality of storage locations and a plurality of address decoder elements, each having a one or more input address connections for mapping to a respective one or more data elements of an input data entity. Decoding by a given one of the plurality of address decoder elements serves to conditionally activate the address decoder element depending on a function of values of the one or more data elements of the input data entity mapped to the one or more input address connection(s) and further depending on an activation threshold. Memory access operations to one of the plurality of storage locations are controlled by two or more distinct ones of the plurality of address decoder elements depending on coincidences in activation of the two or more distinct address decoder elements as a result of the decoding. A method and machine-readable instructions are also provided.

Abstract: Improvements in a bollard speaker with in-ground subwoofer where the bollard contains a first speaker for higher frequencies and the subwoofer that provides lower frequencies that emit from below ground up through the bollard through a grill in the middle or upper portion of the bollard. The in-ground subwoofer provides a structural foundation for the bollard. Placing the subwoofer in an underground housing allows for larger speaker sizes for improved lower frequency response without trying to produce low frequency sounds in a constrained vertical bollard housing pole. The same base subwoofer is used with interchangeable bollards that accommodate both a cylindrical and a square or rectangular above ground bollard. The speaker within the bollard is configurable for omni-directional or directional sound transmission.

Abstract: A syringe-based apparatus includes a housing having an open proximal end and a distal end, a needle coupled with the distal end of the housing, an actuator mechanism coupled with the housing, the actuator mechanism including a syringe body and a plunger, the syringe body and the plunger being insertable into the open proximal end of the housing. A medicament reservoir is defined at least partially by the housing and the actuator mechanism, and a reconstitution fluid reservoir is defined at least partially by the syringe body and the plunger of the actuator mechanism. The plunger is operably configured to move relative to the syringe body to expel the amount of the fluid from the reconstitution fluid reservoir into the medicament reservoir. The actuator mechanism is operably configured to move relative to the housing to expel the amount of the fluid from the medicament reservoir through the needle.

Abstract: An infusion pump for pumping fluid through an administrative set at a desired flow rate over a specified duration, and includes a pumping mechanism for releasably receiving and for exerting a pulsing force on the administrative set, thus pressurizing a portion of the set for creating a flow of fluid from a set outlet. A controller is connected to and is configured for operating the pumping mechanism, the controller determines a pulse frequency based on a volume of fluid infused over a portion of the specified duration and the desired flow rate, outputs a control signal to the pumping mechanism for operating the pumping mechanism based on the determined pulse frequency, determines a first pulse frequency based on the desired flow rate; and adjusts the first pulse frequency based on the volume of fluid infused to provide a second pulse frequency being different from the first pulse frequency.
