摘要:
A transcutaneous energy transfer system, transcutaneous charging system, external power source, external charger and methods of transcutaneous energy transfer and charging for an implantable medical device and an external power source/charger. The implantable medical device has a secondary coil adapted to be inductively energized by an external primary coil at a carrier frequency. The external power source/charger has a primary coil and circuitry capable of inductively energizing the secondary coil by driving the primary coil at a carrier frequency adjusted to the resonant frequency to match a resonant frequency of the tuned inductive charging circuit, to minimize the impedance of the tuned inductive charging circuit or to increase the efficiency of energy transfer.

Preferred embodiments for methods of removing an integrated circuit (“IC”) from a substrate, where the IC is attached to the substrate by multiple solder connections are disclosed. One preferred embodiment of the inventive methods provides the steps of heating the IC and substrate to the reflow temperature for the solder connections and pulling the IC from the substrate by means of a vacuum force. Another preferred embodiment of the inventive method provides the step of shearing the IC from the substrate after the substrate and IC are heated, but before solder reflow temperature has been reached, and where the shearing force may be programmed through a computer controlled servomotor. Preferred embodiments of certain apparatus applying the inventive methods for removing an integrated circuit from a substrate are also disclosed. One preferred embodiment of the inventive apparatus includes a vented pallet to hold the substrate and IC and through which the vacuum force is applied to pull the IC from the substrate without the use of physical clamping or contact forces applied to the substrate or IC. In a further preferred embodiment of the inventive apparatus, shear elements are provided and used with a programmable servomotor for precisely controlling the forces applied to the substrate and IC as a function of time, temperature and translational distance.

Integrated circuit parts to be loaded are guided down an inclined ramp in a guideway for gravity feeding into a storage and transport tube. A tube holder member is attached to the bottom of the ramp; and it has an aperture through it for receiving a tube to be loaded. A blocking device, in the form of a lever arm, is attached to the tube holder member, and extends into the guideway through which the integrated circuit devices travel. When a tube is inserted into the tube holder member, a projection on the lever arm is engaged by the end of the tube to move the lever arm out of engagement with the guideway or any integrated circuit parts in it. When the tube is full of parts, it is removed from the tube holder member and the lever arm drops into place to either rest on the top of the next integrated circuit part in line or to fall into the guideway to prevent further movement of parts into the tube holder member.
摘要:
A method of making an aliphatic polyester prepolymer, comprising: reacting, alone or in combination with other reactants, a diol with at least a first diacid (or a diester of said first diacid) to produce an aliphatic polyester prepolymer. The first diacid is preferably a trans-beta-hydromuconic acid (HMA). In some embodiments, the diol contains at least one ether linkage. In some embodiments the diol is further reacted with at a second diacid, or a diester of said second diacid, wherein said second diacid is different from said first diacid. Prepolymers produced from such processes and articles formed therefrom are also described.

A MEMS fuze having a moveable slider with a microdetonator at an end for positioning adjacent an initiator. A setback activated lock and a spin activated lock prevent movement of the slider until respective axial and centrifugal acceleration levels have been achieved. Once these acceleration levels are achieved, the slider is moved by a V-beam shaped actuator arrangement to position the microdetonator relative to a secondary lead to start an explosive train in a munitions round.
