  • Publication number: 20190245246
    Abstract: A solid state electrochemical battery fabrication device and a method of creating the solid state electrochemical battery are provided. There is a first chamber comprising a first magnetron and a second chamber comprising a second magnetron, coupled to the first chamber. There is a third chamber comprising a vapor source for a polymer deposition, coupled to the second chamber. A Knudsen cell is coupled to the third chamber and configured to deposit lithium on a battery being fabricated. A linear hollow shaft connects the first, second, and third chambers, and provides a hermetic seal. A first telescopic arm having a housing is coupled to a first end of the hollow shaft and configured to extend out of its housing from the first chamber to the second chamber.

  • Publication number: 20190244815
    Abstract: A hard mask and a method of creating thereof are provided. A first layer is deposited that is configured to provide at least one of a chemical and a mechanical adhesion to a layer immediately below it. A second layer is deposited having an etch selectivity that is faster than the first layer. A third layer is deposited having an etch selectivity that is slower than the first and second layers. The third layer has a composite strength that is higher than the first and second layers. A photoresist layer is deposited on top of the third layer and chemically removed above an inner opening. The third layer and part of the second layer are anisotropically etched through the inner opening. The second layer and the first layer are isotropically etched to create overhang regions of the third layer.

  • Publication number: 20100124327
    Abstract: An acoustic pass through is provided in telephone handsets for sounds transmitted from a hands free operation speaker laid out underneath the handset. One or more cutouts in a middle portion of the handset in various shapes such as rectangular, round, elliptical, and similar allows enhanced sound quality when the speakerphone feature is used and flexibility in handset design.

  • Patent number: 4912762
    Abstract: A method for simplifying key management in situations where unique cryptographic keying relationships are required end-to-end between pairs of parties and a symmetric encryption algorithm is to be used. It is useful in cases where the parties come from disjoint subsets of the total population of parties. The method provides some of the characteristics of a public key crypto system (PKS) utilizing the public identities of the parties as part of the key, but lacks the property of PKS which allows a party to independently generate a secret key which is known only to that party.
