Abstract: A disposable safety razor includes a blade housing and a blade disposed within the blade housing to expose a cutting edge suitable for shaving. The blade housing and the blade have complementary characteristics which result in destruction of the blade upon an attempt to remove the blade from within the blade housing. In this regard, the blade housing comprises a substantially rigid housing and the blade comprises a brittle ceramic blade. The safety razor further includes a handle attached to the blade housing. The handle is made from a pliable plastic material that forms an enclosure filled with a dispensable liquid.

Abstract: A rechargeable smoke and carbon monoxide detector is provided. The base of the detector has a battery formed therein that is charged when connected to a power source, such as a 110-volt light bulb socket. The detector is further configured to receive a 110-volt light bulb so as to not eliminate the use of the light socket as a light source. Additionally, the detector may include one or more warning devices such as an ionization or photoelectric sensor, speaker, or light source. A power indicator LED, a smoke indicator LED, and a carbon monoxide indicator LED all provide visual notification that the detector is functioning properly.

Abstract: A smoke detection and escape indication system includes a master controller in communication a base unit and a satellite unit. The base unit and the satellite unit are each in wireless communication with one another and include a wireless receiver, a wireless transmitter, a sensor for detecting a hazard and an escape indication mechanism. The base unit and the satellite unit cooperate to indicate an escape route by coordinating respective escape indication mechanisms in the event that one of the units detect a hazard.

Abstract: A smoke detector system having a base unit and multiple satellite units is provided. The base unit detects various hazards, i.e., smoke or carbon monoxide, and broadcasts a radio frequency signal to activate warning devices on the various satellite units. The satellite units include a radio frequency receiver to receive the signal broadcasted by the base unit. The warning devices include a laser cannon, a speaker, a strobe light, and a wireless camera separately or in combination with other warning devices. Alternatively, each base unit may include one or more of the warning devices and a radio frequency receiver, and each satellite unit may include the detection devices and a radio frequency transmitter. In this way, each device in the system may activate warning devices in each other device in the system when a hazard is detected.
