Abstract: A position-sensing waking system and method includes an ear plug for slidably inserting into an ear of a person, a housing rotatably connected with the ear plug, an alarm mechanism for generating an alarm sound, a detection switch disposed inside the housing, a control circuit for controlling the position-sensing waking system, and a battery for supplying power to the position-sensing waking system, the housing containing the alarm system, the system switch, the detection switch, the control circuit and the battery, wherein the detection switch is activated according to a movement of the ear to generate the alarm sound by the alarm mechanism.

Abstract: A position-sensing light and alarm system includes an attachment for movably mounting to the fishing rod; a housing fixedly connected to the attachment, the housing including a light source for illuminating light, a sound source for generating an alarm sound, and a battery for supplying power to the system; a first switch for selectively controlling the system; a second switch for selectively controlling the light source; a mercury switch attached to the housing and being rotatable with respect to the housing to achieve a first position, the mercury switch achieving a second position upon a movement of the fishing rod; and a control circuit disposed in the housing, whereby at least one of the light source and the sound source is activated in response to the mercury switch being at the second position.

Abstract: A self-extinguishing cigarette includes a cigarette body, a deformed sleeve made of vinyl plastics for slidably moving around the cigarette body, and an annular stopper attached on one end of a cigarette filter, whereby, upon moving the sleeve to a flame position of a lit end of the cigarette body, the lit cigarette is immediately extinguished by being squeezed and wrinkled by the sleeve.
