Abstract: Described herein is mechanically decoupling of an electromechanical transducer from a common substrate, enabling multiple transducers to be surface mounted to a common substrate such as a printed circuit board (PCB) without experiencing mechanical cross-coupling. The decoupling of the transducer from the substrate enables the transducers to be attached without reducing the efficiency of acoustic transduction. The design of the mount enables it to be assembled in an automated manner with pick and place tools.

Abstract: A system and method is provided for qualitative analysis of baseband building automation networks. The system may include a processor configured to carry out a plurality of tests on a serial communication network that includes at least one field device that carries out building automation communications on the network. A first test may include: transmitting a series of queries for devices on the network, in which the queries are transmitted at incrementally lower transmission signal levels until message loss is detected; and determining a first lower signal level at which transmissions of queries occur without message loss on the network. In addition, the processor may be configured to determine and output on a display device at least one classification of the relative quality of the network with respect to at least one predetermined scale of relative network quality based at least in part on the first lower signal level.

Abstract: Methods and systems for displaying information derived from identification documents associated with individuals are disclosed. In some embodiments, the system first scans or retrieves identification information from an identification document. The system then receives information of an issuer of the identification document, information of a current location of the identification document, and information of a proposed use of the identification information. The system then receives a set of rules from a database based on the information of the issuer, the current location, and the proposed use. Based on the set of rules, the system processes the retrieved identification information so as to form redacted or processed identification information. The system then displays the redacted identification information.

Abstract: A containment apparatus for protecting a surrounding environment from leaks originating from a stuffing box is provided. In some embodiments, the containment apparatus utilizes a float switch to switch off a pump associated with the stuffing box when the level of a liquid in the vessel exceeds a predetermined level. The switch can communicate ultrasonically with a receiver that relays a message to a user. In some embodiments, the vessel comprises two half vessels that are lined by a metal frame along their mating edges.

Abstract: Isolated capacitance line voltage sensing is provided that avoids metal-to-metal contact for voltage sensing of a power signal present on a power wire. An external conductor is positioned by the power wire, creating a capacitor with the power wire conductor, insulation, and external conductor. The capacitance is used to measure the electric field, indicating a voltage level for the powered wire. The impedance mismatch caused by the capacitance is transformed. The impedance transformation circuit may be integrated with the external conductor, allowing voltage sensing by a voltage meter having a lower input impedance. A manual or automatic calibration circuit may be provided to ensure the measured voltage represents the actual voltage on the power wire.

Abstract: An apparatus for containing leaks from a stuffing box on a wellhead production assembly, the apparatus comprises a containment vessel consisting of two half shells that are joined below the stuffing box. Additionally, the apparatus comprises a transparent lid having an upper opening to receive a polished rod extending from the stuffing box. The lid is secured to the containment vessel in a liquid tight manner such that the stuffing box is substantially isolated from the environment so that any leaks originating from the stuffing box will be contained in the apparatus.

Abstract: A fish gig is provided. The fish gig may include a retractable barb, wherein the retractable barb is operably connected to a handle configured for extending and retracting the retractable barb.

Abstract: Systems and methods for conducting business using competitive bidding and verification of yield restricted escrows and investments are disclosed. The methods can include automatically transmitting a request for proposal (RFP) from an issuer to at least a predetermined minimum number of potential bidders. According to certain embodiments, the RFP can include written bid specifications including an amount of money made available to be used to purchase one or more open market securities (OMS), a settlement date, proposal due date, a required cash flow, and an indication of OMS type eligibility. According to certain embodiments, the method can include automatically transmitting to the issuer a plurality of bids to provide one or more OMS to be purchased using the escrow amount in conformity with the written bid specifications, from at least a predetermined minimum number of bidders.
