High frequency chip packages with connecting elements

A radio frequency chip package is formed by assembling a connecting element such as a circuit board or flexible circuit tape having chips thereon with a bottom plane element such as a lead frame incorporating a large thermally-conductive plate and leads projecting upwardly from the plane of the plate. The assembly step places the rear surfaces of the chips on the bottom side of the connecting element into proximity with the thermal conductor and joins the conductive traces on the connecting element with the leads. The resulting assembly is encapsulated, leaving terminals at the bottom ends of the leads exposed. The encapsulated assembly may be surface-mounted to a circuit board. The leads provide robust electrical connections between the connecting element and the circuit board.

Flexible Circuit for Downhole Antenna

An antenna for an electromagnetic tool having a longitudinal axis and a core. The antenna includes a flexible dielectric substrate flexibly conformed about the core and an electrical conductor disposed on the dielectric substrate. The electrical conductor is disposed on the substrate such that the antenna has a dipole moment having any desired direction relative to the longitudinal axis of the tool.

Compact integrated touch panel display for a handheld device

InactiveUS6965375B1Minimizing length of busReduction in size of handheldTransmission systemsCathode-ray tube indicatorsFlexible circuitsElectrical connection
A handheld device with a compact integrated touch panel is disclosed. A handheld device incorporating a touch panel display requiring electrical connections is reduced in size by incorporating electrical pathways within the support structure of the touch panel display, obviating the need for a flex circuit extension from the touch panel display for connection to the handheld device. A further reduction in size is obtained by providing an inherent visually homogeneous perimeter for the touch panel display by matching the colors of the conductive and dielectric materials, thereby eliminating the need for a bezel.

Body composition, circulation, and vital signs monitor and method

The invented non-invasive vital signs monitor is in a flexible, nominally flat planar form having integral gel electrodes, a sticky-back rear surface, an internal flex circuit capable of sensing, recording and playing out several minutes of the most recently acquired ECG waveform data and a front surface that includes an outplay port. The invented non-invasive body composition ‘risk’ monitor includes a measurement device for monitoring one or more variables including body fluid mass, dehydration, respiratory rate, blood pressure, bio-impedance, cardiography such as cardiac output, and body conformation parameters. The risk monitor may be provided in a lightweight carrying case into which the vital signs monitor plugs. Finally, a lightweight portable probe or transducer containing a transmissive or reflective electro-optical emitter and receptor in the infrared spectrum is fitted on a subject's finger or toe. Associated electronics energize and monitor the probe, detect cardio-rhythmic fluctuations therefrom, and process digital data over a prescribed window to produce a non-invasive, qualitative or quantitative measure of the subject's circulation. In accordance with one embodiment of the invention, a simple tri-color LED array is used to indicate the subject's circulation as being normal, reduced, or borderline. Thus the vital signs, bio-impedance, and circulation monitors may be independent or they may be integrated into one portable, non-invasive device that can concurrently monitor and locally display or remotely convey important patient data including circulation data to a local subject or physician or to / from a remote patient medical data center via wireless telemetry for oversight, treatment and possible intervention by a remote physician.

Implantable flexible circuit leads and methods of use

Devices, systems and methods are provided for stimulation of tissues and structures within a body of a patient. In particular, implantable leads are provided which are comprised of a flexible circuit. Typically, the flexible circuit includes an array of conductors bonded to a thin dielectric film. Example dielectric films include polyimide, polyvinylidene fluoride (PVDF) or other biocompatible materials to name a few. Such leads are particularly suitable for stimulation of the spinal anatomy, more particularly suitable for stimulation of specific nerve anatomies, such as the dorsal root (optionally including the dorsal root ganglion).

The light guide comprises a reflective surface formed on an inner wall of the housing, a reflector having a concave reflective surface which is disposed at one end of the housing so as to surround the LEDs or a micro-lens array disposed in front of the LEDs with each micro lens aligned with the LED.

Touch pad with flexible substrate

A touch sensor device is provided that uses a flexible circuit substrate to provide an improved input device. Specifically, the present invention uses a touch sensor controller affixed to the flexible circuit substrate, which is coupled to a sensor component to provide a flexible, reliable and cost effective touch sensor suitable for a wide variety of applications. In one embodiment the touch sensor uses a flexible circuit substrate that provides relatively high temperature resistance. This allows the touch sensor controller to be affixed using reliable techniques, such as various types of soldering. The sensor component can comprise a relatively low-temperature-resistant substrate that can provide a cost effective solution. Taken together, this embodiment of the touch sensor provides reliability and flexibility at relatively low cost.

Fingerprint identification module, terminal device and assembling method

The present invention provides a fingerprint identification module, a terminal device and an assembling method, and relates to the design field of the fingerprint module of the terminal device. The invention aims to solve the stack design problem of the structure of the terminal device due to the fact that the internal structural space of the terminal device is occupied by one part of the fingerprint identification module in the prior art. The fingerprint identification module comprises a fingerprint chip, a fingerprint cover plate, a flexible circuit board, a reinforcing plate and a decorative ring arranged at the periphery of the fingerprint chip. The first connection part of the decorative ring is connected with the first end of the fingerprint chip and is also in contact connection with the fingerprint cover plate. The second connection part of the decorative ring is connected with the second end of the fingerprint chip and is also in contact connection with the fingerprint cover plate. Meanwhile, the second connection part of the decorative ring is fixedly connected with the reinforcing plate. The present invention also provides a terminal device and an assembling method. According to the technical scheme of the invention, the second connection part of the decorative ring is fixedly connected with the reinforcing plate. Therefore, fingerprint identification module becomes thinner in thickness. The internal structural space of the terminal device is saved when the fingerprint identification module is installed through being matched with the terminal device.
