  • Safety device for lithium-ion-polymer battery
    Patent number: 6175213
    Abstract: A battery is comprised of a rigid, plastic housing defining a generally rectangular interior cavity, and an essentially flat interior surface. A battery rechargeable electric cell has a flexible outer packaging, an electrically conductive thermoset adhesive film, and is contained within the cavity. The cell is generally rectangular in shape and has a flat outer surface and two leads extending through the housing. The cell has a normal configuration when experiencing normal operating conditions, and an abnormal configuration when experiencing abnormal operating conditions. A membrane switch is disposed between the flat interior surface of the housing and the flat outer surface of the cell. The switch has at least one lead extending through the housing. The switch has a first electrical condition when the cell has the normal configuration and a second electrical condition when the cell has the abnormal configuration.

  • Method of connecting batteries to electronic circuits
    Patent number: 6056185
    Abstract: A method of securing a metal lead of a polymer battery to a flexible circuit, comprising the steps of positioning a metal lead of a polymer electrolyte battery onto a connection pad of a circuit; clamping the metal lead and the connection pad between two weld fixtures of an ultrasonic welder; compressing the metal lead and connection pad between the two weld fixtures to establish a pressure of about 44.9 psi to about 30.8 psi; and vibrating the weld fixtures at a frequency of about 20 kHz for about 0.1 seconds to about 2.0 seconds.

  • Flexible printed circuit sensor assembly for detecting optical pulses
    Patent number: 5390670
    Abstract: A flexible sensor assembly for detecting optical pulses in which said sensor assembly comprises a flexible printed circuit having mounted thereon at least one light emitting diode and at least one photoelectric detector connected to different circuit patterns with an insulative tape secured over the circuit and components and wherein the flexible sensor is adapted to be folded so that the photoelectric detector can be spaced from and disposed over the light emitting diode.
