Patent number: 8652971Abstract: A MEMS device having a device cavity in a substrate has a cavity etch monitor proximate to the device cavity. An overlying layer including dielectric material is formed over the substrate. A monitor scale is formed in or on the overlying layer. Access holes are etched through the overlying layer and a cavity etch process forms the device cavity and a monitor cavity. The monitor scale is located over a lateral edge of the monitor cavity. The cavity etch monitor includes the monitor scale and monitor cavity, which allows visual measurement of a lateral width of the monitor cavity; the lateral dimensions of the monitor cavity being related to lateral dimensions of the device cavity.Type: GrantFiled: March 5, 2012Date of Patent: February 18, 2014Assignee: Texas Instruments IncorporatedInventors: Ricky Alan Jackson, Walter Baker Meinel, Karen Hildegard Ralston Kirmse

Publication number: 20120225559Abstract: A process of forming a MEMS device with a device cavity underlapping an overlying dielectric layer stack having an etchable sublayer over an etch-resistant lower portion, including: etching through at least the etchable sublayer of the overlying dielectric layer stack in an access hole to expose a lateral face of the etchable sublayer, covering exposed surfaces of the etchable sublayer by protective material, and subsequently performing a cavity etch. A cavity etch mask may cover the exposed surfaces of the etchable sublayer. Alternatively, protective sidewalls may be formed by an etchback process to cover the exposed surfaces of the etchable sublayer. Alternatively, the exposed lateral face of the etchable sublayer may be recessed by an isotropic etch, than isolated by a reflow operation which causes edges of an access hole etch mask to drop and cover the exposed lateral face of the etchable sublayer.Type: ApplicationFiled: March 5, 2012Publication date: September 6, 2012Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Ricky Alan JACKSON, Walter Baker MEINEL, Karen Hildegard Ralston KIRMSE

Patent number: 7765161Abstract: A system and method are disclosed for providing a plurality of payment services to facilitate electronic commerce. In one embodiment, services are provided within the context of a four-corner trust model comprising a buyer and a seller that engage in an on-line transaction. The buyer is a customer of a first financial institution. The first financial institution acts as a certificate authority for the buyer and issues the seller a hardware token including a private key and a digital certificate signed by the first financial institution. The seller is a customer of a second financial institution. The buyer uses its private key to sign payment instructions that are forwarded to the first or second financial institution for execution. The message may be forwarded to the first financial institution indirectly via the seller and the second financial institution.Type: GrantFiled: May 4, 2004Date of Patent: July 27, 2010Assignee: Identrust, Inc.Inventors: Mary Keenan McKenney, Markus Walch, Walter Baker, III, Oliver Storch, Peter Josef Eduard Landsmann, William John Jetter, Margaret Miu-Ling Wong, William Isaac Cameron

Publication number: 20060064311Abstract: A high speed mailing system that utilizes a single postal security (PSD) device in conjunction with multiple printing modules is provided. The control unit with which the PSD is associated is coupled to each of the printing modules through a multiplexer capable of switching between each of the printing modules. During initialization of the system for each mail processing session, the control unit establishes a secure communication session with each printing module individually through the multiplexer. Thus, the control unit can generate and provide indicia that can be printed only on the specific printing module that is currently in use. The multiplexer can switch between printing modules during operation of the mailing system, thereby always keeping one printing module in use while allowing the printing module that is not currently being used to perform any necessary maintenance operations, without having to stop the processing of mail pieces.Type: ApplicationFiled: September 20, 2004Publication date: March 23, 2006Applicant: Pitney Bowes IncorporatedInventors: Walter Baker, Konstantin Kodonas, John Steinmetz
