Abstract: An in-cord detachable ear hanger for an in-ear phone is provided. The ear hanger can protect the in-ear phone from being pulled off position from the user's ear when the user or any nearby person accidentally pulls the cable connected to the earphone set in a jerked manner. The ear hanger includes a shank body, a substantially hook-like portion, and a cable grasping means in substantially anchor-like shape. The hook-like portion is shaped in such a manner as to snugly fit to the back of a user's ear. The cable grasping means can grasp a selected portion of the cable, by which a margin length of the cable is left between the ear hanger and the speaker element inserted in the user's ear. During use of the in-ear phone, when any part of the cable other than the margin length is pulled in a jerked manner, the ear hanger would be pulled off the ear, but in most of the cases the speaker element would still stay in position in the user's ear.

Abstract: A portable hands-free telephone converter that allows a user to speak on the telephone without using the hands to hold a handset or the like. The telephone converter includes a first coupler for coupling the telephone converter to the receiver of the handset, a second coupler for coupling the telephone converter to the transmitter of the handset, a converter, coupled via the first coupling means and the second coupling means to the handset, for receiving the incoming voice from the receiver and outputting the user's voice to the transmitter, and a controller, coupled to the converter, for amplifying the user's voice signal and for amplifying the incoming voice signal received by the converter from the handset receiver.

Abstract: An in-ear type earphone according to the present invention includes an in-ear type speaker element and a cable disposed externally of the earphone. The cable is coupled at one end to the speaker element such that the cable hangs freely from the speaker element. The opposite end of the cable is coupled to a plug. The plug operatively connects the earphone to a sound signal source. A sliding round shaft is rotatably mounted at one end of the speaker element. A sliding sleeve receives an opposite end of the sliding round shaft and allows it to move along a longitudinal axis. The earphone also has an ear hanger with a helix stopper end, a curved hook section, and a lobule stopper end integrally formed and contoured to the general shape of a human ear. The helix stopper end is mounted to the sliding sleeve in a fixed manner.

Abstract: A lighter provided with a cigarette extinguisher which is capable of cutting and extinguishing a burning head of a cigarette safely. The cigarette extinguisher comprises an upper cut element, a torsion spring, a tongue, a lower cut element and a pivot pin. The pivot pin pivotally connects the upper cut element and the lower cut element to facilitate the relative pivotal movement of the upper cut element and the lower cut element, the relative pivotal movement affects the cutting-off of a cigarette head which is inserted into the space between the upper cut element and the lower cut element.

Abstract: A real-time speed display apparatus for displaying vehicle speed with different colors of light has a speed detector for detecting the speed of revolution of the transmission shaft of a vehicle and outputting a speed signal with its pulse rate varied as a function of the revolution speed. The speed signal is converted into a periodic signal through a timing gate under the control of a clock signal generated by a clock generator. A counter is used to count the number of the pulses within each period of the interval signal, based on which an encoder outputs a corresponding display control signal and transmits it to respective display drivers. Upon receipt of the display control signal, the drivers are started to drive the respective light units. Therefore, different color light is formed on a screen by combination of light emitted by the driven light units.
