Abstract: Examples described herein provide a method for overspeed protection of a motor of a gate crossing mechanism. The method includes monitoring, by an overspeed protection circuit, a voltage across a first Zener diode and a second Zener diode. An anode of the first Zener diode is connected to an anode of the second Zener diode. The method further includes, responsive to determining that a Zener voltage threshold is exceeded, allowing a current to flow into a gate pin of a triac. The triac controls the motor of the gate crossing mechanism.

Abstract: A system for determining alignment of a signal includes a light assembly comprising a light source operated by an electronic circuit, a first position sensor configured to measure a geographical direction of the light assembly, a second position sensor configured to measure a tilt angle of the light assembly, and a light communication device configured to receive measurements of the first position sensor and the second position sensor, and wherein the light communication device is configured to evaluate the measurements and determine alignment of the light assembly based on predefined tolerance thresholds for the geographical direction and tilt angle.

Abstract: A highway grade crossing gate mechanism having a smart cam system capable of measuring a parameter of the gate mechanism in real time is provided. The gate mechanism includes a DC motor, a cam system, and a controller. The DC motor is coupled to a main shaft for driving a gate arm between a vertical position and a vertical position. The cam system includes manually adjustable cams coupled to the main shaft that move contacts to open or close at some preset angular rotation in order to set operational features of a crossing gate. An internal sensing device is disposed internal to the cam system measuring a parameter of the gate mechanism in real time. A controller controls the motor and receives and stores the parameter. The parameter may be transmitted to an external network giving accurate feedback of the state of the gate mechanism in real time.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for conducting cardless payment transactions. One of the methods includes receiving from a merchant computer an indication of a payment transaction by a user associated with a mobile phone number. A text message is provided to a device associated with the mobile phone number requesting approval for the payment transaction, wherein the message includes an approval code. A message is received from the device associated with the mobile phone number. If the text message from the device associated with the mobile phone number includes the provided approval code, account information associated with the mobile phone number is obtained, authorization for the payment transaction is obtained using the account information, and notification of authorization of the payment transaction is provided to a merchant conducting the payment transaction.

Abstract: Processing cardless payment transactions is described. In an example, a server system can receive a message from a mobile device of a user that includes a code identifying a merchant and can verify the identities of the merchant and the user based at least in part on account data stored in association with the server system. The server system can provide, to a merchant computer of the merchant, user information associated with the user account and can receive from the merchant computer, a request to authorize the cardless payment transaction. The server system can obtain authorization for the cardless payment transaction using account information associated with the merchant account and/or the user account, and can provide, to the merchant computer, notification of the authorization of the cardless payment transaction.

Abstract: A magazine-based data storage library is described that includes plurality of chambers each adapted to hold a magazine, that in turn, is adapted to hold a plurality of tape cartridges. The storage library further includes a tape drive adapted to read and write data to and from tape cartridges. The storage library further includes a vacant chamber that shifts from a first chamber when a recently used magazine is disposed therein to a second chamber when a new magazine is withdrawn there from. The recently used magazine most recently being withdrawn from a different chamber than the first chamber where it is later disposed.

Abstract: A storage library is described that includes a tape magazine that possesses at least one spare slot and a number of other addressable slots that each contains a tape cartridge. Each addressable slot is mapped and made known to a host when the host is linked to the storage library. One of the addressable slots contains a tape cartridge that prior to being mapped as an addressable slot was formerly a spare slot unmapped to the host and the current spare slot was formerly mapped as an addressable slot.

Abstract: The invention relates to improvements relating to cancer therapy based on the identification of a number of regions of CPG2 which contain epitopes which appear to be involved in the production of a host immune response and which may be modified to alter the immunogenicity in patients. Production of fusions of CPG2 with an antibody, where the CPG2 protein has been tagged provides a CPG2 protein which has reduced immunogenicity. By using partially glycosylated enzyme obtainable by P. pastoris expression, the efficacy of antibody-CPG2 fusions is enhanced.

Abstract: A merchandise display stand for displaying a plurality of products in a vertical arrangement.

Abstract: A method for carrying out a well treatment in a well (e.g. fracturing, sand control, etc.) wherein a high-viscosity treatment fluid containing a gel (e.g. a polymeric gelling agent) is flowed down the well along with a bacteria selected from the generic classes of Enterococcus and Corynebacterium or a mixture of the two, which is capable of digesting and/or cleaving the gel to reduce the viscosity of the gel at the conclusion of the well treatment.
