Abstract:
There is disclosed a multi-flashlamp article capable of providing both highly intense audible and visual signals. The article is ideally suited for use as an intrusion alarm and includes a combustible member within the assembly's light-transmittable housing. A prestressed spring actuates the combustible by deforming a tubular primer having a quantity of fulminating material therein. This deflagrating material ignites a second quantity of fulminating material within the combustible's container to effect a suitable audible signal.
Abstract:
A patient support apparatus includes a frame, a support surface for supporting a patient, and a nurse call interface adapted to provide an interface between a bed and a wall-mounted nurse call outlet having a plurality of pins to thereby allow a patient supported on the bed to communicate with a remotely positioned nurse. The nurse call interface coordinates the duplex signals of the bed's microphone and speaker with the half duplex nurse audio signals from the nurse call system. More particularly, the interface includes a nurse call audio channel communicatively coupled to first and second audio pins of the plurality of pins of the nurse call outlet, a bed microphone channel to a bed microphone, a bed speaker channel to a bed speaker, and a switch controller adapted to selectively connect the nurse call audio channel to the bed microphone channel or to the bed speaker channel.
Abstract:
The work area advanced warning system is for use on the work site to give warning of impending danger in order to give time for workers and others to avoid the danger before the damage. Dangers are sensed by the use of contained exploding charges, smoke and horns or sirens activated by remote control to create unnatural comotion thus alerting the senses to potential loss.
Abstract:
A multilamp flashlamp assembly capable of emitting highly intense audible and visual signals and particularly adapted for alarm situations. The assembly utilizes percussive flashlamps which operate in conjunction with a respective plurality of pyrotechnic devices located about the assembly's transparent housing. Each device provides an audible signal in response to the energy received from the respective lamp when the lamp is fired.
Abstract:
A flashlamp article activation means which includes a casing, an activator movably oriented within the casing, and an engagement member for engaging the activator to cause it to move within the casing and activate the flashlamp article positioned on the casing. A helical spring is used to bias the activator away from the article. An ideal use for the invention is within an intrusion alarm system.
Abstract:
A mechanism for activating a plurality of flashlamps in a flashlamp article (e.g., MAGICUBE) in response to external actuation (e.g., the opening or closing of a door) thereof. To prevent accidental actuation, the mechanism includes a safety device in the form of an elongated pin which inserts within a pair of aligned openings within the mechanism to positively engage and retain the mechanism's movable activator. In one embodiment, the pin is also attached via a cord to the mechanism's spherical ball engagement member which causes movement of the activator.
Abstract:
Activation means for activating at least one percussive flashlamp unit located within a flashlamp article. An activator moves within a casing when released by a pivotal retaining arm to engage and effect release of the flashlamp unit's striker spring. The retaining arm provides release of the activator in response to external actuation, e.g., the opening of a door or window.
Abstract:
Means for activating a multilamp flashlamp article in response to movement of a door. An activator having several upstanding engagement members is operatively joined to the base portion of a two-part housing. Movement of a pivoted arm portion of the housing toward the base causes a casing member to move about the activator whereby each of the engagement arms will activate a respective lamp unit within the flashlamp article. The invention is ideally suited for use within an intrusion alarm system.
