This invention includes an electronic accessory having a single button that actuates all of its control features. In one embodiment, the accessory is a MP3 player wherein songs are stored on a multimedia card. Once the card has been loaded an inserted, the MP3 player is coupled to an energy source. In a preferred embodiment, the energy source is preferably a cellular telephone. After coupling, all of the functions of the MP3 player are controlled with a single button. In a preferred embodiment, power is actuated by pushing the button for one second. Volume is adjusted by toggling the button laterally. Tracks are selected by pushing the button quickly while power is applied. Power is turned off by depressing the button for two seconds or more.

A switchable power supply includes a moveable electrical plug holding member that has a first position, which places an electrical plug pair in position for use with a first voltage standard, and a second position, which places the electrical plug pair in position for use with a second voltage standard. A switch is in a first state when the moveable electrical plug holding member is in the first position and is in a second state when the moveable electrical plug holding member is in the second position. When the switch is in the first state, a voltage modifier circuit generates a first output voltage and when the switch is in the second state, the voltage modifier circuit generates a second output voltage.

Battery for a laptop computer

An electronic device (100) includes electrical circuitry (130), a housing (105) in which the electronic circuitry (130) is situated, a cover (110) for enclosing the electrical circuitry (130) within the housing (105), and a tamper proof safety circuit (120) coupled to the electrical circuitry (130) for rendering the electronic device (100) inoperable when the housing (105) and cover (110) are disassembled.

Tamper proof safety circuit

A leaded component (10) is provided with first and second leads (14 & 16). The leads are formed with stopping deviations (26 & 28) which prevent the leads from being inserted into a circuit board (38) beyond the stopping deviations. The leads may also be provided with retaining deviations (34 & 36) which function to retain the component on the circuit board. Further, the stopping deviations may be formed so as to indicate the polarity of a component, and finally, the stopping deviations may be provided with mounting portions (50 & 52) so that the leaded component may be surface mounted on a circuit board (54).

Electrical component having formed leads

A contact block (10) is provided with a first ledge (34) and a second ledge (38) that deflectably engage a first edge (46) and a second edge (48) of an opening (44) in the housing (42) of an electrical device. The contact block (10) mechanically supports at least one electrical contact (14) to provide a contact surface (18) whereby the first electrical device (40) may be electrically interconnected with a second electrical device (60). The contact block (10) is snapped into place during assembly until it is secured during a final assembly operation.

A multi-faceted energy director (15) is provided for joining two plastic workpieces (12) (14) by an ultrasonic welding method. The energy directors (15) include at least first and second facets (16) (17) arranged in perpendicular fashion, so as to engage two surfaces. A method for joining at least two ultrathin plastic pieces, including the multifaceted energy director, is also provided.

Energy director for ultrasonic weld joint

A battery device (100) has integral circuit substrate packaging. The battery device (100) has one or more energy cells (122), and a substrate (105) having an integral battery circuit (130) electrically coupled to the one or more energy cells (122). The substrate (105) forms a housing for the one or more energy cells (122).

Battery device with integrated circuit substrate packaging

A removable battery package (10) having a latch mechanism (32) for attaching the battery package (10) to a radio (18) is provided. The battery package (10) comprises a housing (15) having an interior surface (30), an exterior surface (14) and sidewalls (16). Engagement means (32) are located on the interior surface (30) of the housing (15) for engaging a receiving means (22) located on the radio (18). Activating means are provided for activating the latch wherein the activating means comprises a recessed portion (12) located in the exterior surface (14) of the housing (15) transverse to the engagement means(32). The recessed portion (12) is designed so that by pressing the sidewalls (16) of the housing (15) a portion of the housing (24) is temporarily outwardly deformed thereby disengaging the engagement means (32).
