Patent number: 7315037Abstract: An infrared identification device includes a light emitting panel member that receives light from an infrared light source for conduction within the panel member and emission from a light emitting surface area on one side of the panel member, which is relatively easy to detect at night when viewed through night vision equipment. The device may be capable of functioning in an interrogation mode, allowing the device to be activated remotely by a predetermined signal frequency, code signal or pulse signal and send out a signal response.Type: GrantFiled: January 4, 2006Date of Patent: January 1, 2008Assignee: Lumitex, Inc.Inventors: David J. Page, Brian M. Spahnie

Patent number: 6802277Abstract: A emergency sign emits a non-electrical light and sounds a non-electrical alarm when an elevated level of heat is sensed, such heat from a fire, to provide a combined light and a sound alert signals. The light results from the mixing of a chemical compound having chemiluminescent properties. The light illuminates indicia located on the face plate of the sign. The alarm is sounded by releasing compressed gas from a cartridge and directing the released gas through a whistle.Type: GrantFiled: April 11, 2002Date of Patent: October 12, 2004Inventors: Durell Clay, Alfonso Clay

Patent number: 4771724Abstract: A non-pyrotechnic lighting device is disclosed whereby intrusion into a restricted area can be monitored and detected by the use thereof. Triggering of the device is effected remotely by the unsuspecting subject.Type: GrantFiled: June 18, 1987Date of Patent: September 20, 1988Assignee: American Cyanamid CompanyInventors: Bruce H. Baretz, C. Dexter Ware

Patent number: 4449474Abstract: A personal security device is disclosed which comprises a trigger actuated aerosol canister contained in a two-piece telescoping housing. The canister contains a pressurized offensive odor containing gas such as mercaptoethanol which, when ejected from the canister, emits a loud shrieking noise. Additionally, the gas may, as an additional additive, contain a suspension of fine solid or liquid particles of paint or stain so that the device when actuated, discourages a potential rapist or attacker with offensive odor and noise and also identifies him with a stain. In one preferred embodiment, the telescoping housing also includes a flash-type light which is actuated by the same triggers which actuate the canister. The telescoping housing has a key ring attached at one end and may also have a mechanical whistle at the other end.Type: GrantFiled: August 13, 1982Date of Patent: May 22, 1984Assignee: Suzi Stone Enterprises, Inc.Inventor: James F. Mariol

Patent number: 4230450Abstract: 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.Type: GrantFiled: May 4, 1979Date of Patent: October 28, 1980Assignee: GTE Products CorporationInventor: Randall H. LeFever

Patent number: 4130081Abstract: 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.Type: GrantFiled: June 6, 1977Date of Patent: December 19, 1978Assignee: GTE Sylvania IncorporatedInventors: Ronald G. Blaisdell, Harold H. Hall, Jr., Harold L. Hough

Patent number: 4130082Abstract: 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.Type: GrantFiled: June 6, 1977Date of Patent: December 19, 1978Assignee: GTE Sylvania IncorporatedInventors: Andre C. Bouchard, Harold H. Hall, Jr., Robert J. Patton, Thomas J. Sentementes

Patent number: 4130083Abstract: 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.Type: GrantFiled: June 6, 1977Date of Patent: December 19, 1978Assignee: GTE Sylvania IncorporatedInventors: Andre C. Bouchard, Harold H. Hall, Jr.

Patent number: 4116615Abstract: 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.Type: GrantFiled: October 5, 1977Date of Patent: September 26, 1978Assignee: GTE Sylvania IncorporatedInventors: Harold H. Hall, Jr., Andre C. Bouchard
