Abstract: In one embodiment, a solid state drive (SSD) with power loss protection (PLP) includes a SSD controller, a secondary controller and a power circuit configured to supply power to the SSD from a power source during normal operation and backup power from a backup power source in response to a loss of power supplied by the power source. In the event of a loss of power, the secondary controller is configured to track the holdup time, or duration of time for which the primary controller can operate on backup power. In one embodiment, the holdup time tracked by the secondary controller is stored in a non-volatile memory in communication with the secondary controller.

Abstract: The present invention concerns electronic payment apparatus. More particularly, but not exclusively, this invention concerns electronic payment apparatus, and methods and systems for making electronic payments. An apparatus for conducting a financial transaction is provided. The apparatus comprises a smart device with an application. The smart device has a first configuration in which the application displays account information, and a second configuration in which the smart device displays an optically readable transaction authorisation code. The transition between the first configuration and second configuration is effected by changing the orientation of the smart device.

Abstract: The present invention relates to a method of forming a surface covering for example wallpaper or a floor covering and an apparatus for forming a surface covering, in which a surface covering raw material is supplied, the surface covering raw material comprising a substrate and a resin layer comprising a resin and a carrier liquid, the resin being dispersed in the carrier liquid and being capable of gelling or curing with the carrier liquid. A pattern is then applied to the resin layer by inkjet printing, and the surface covering raw material with the pattern formed on the resin layer is heated to gel or cure the resin layer to thereby prepare a surface covering.

Abstract: A system includes a transaction handler, a data warehouse to store transaction data recording transactions processed at the transaction handler and to store account data identifying an account of a user, and a portal to receive a user selection of a first portion of an announcement of a reward. The portal tracks user interactions associated with the announcement to determine whether the user is qualified for the reward. Upon a determination that the user has completed the user interactions for the reward, the transaction handler provides the reward to the account of the user via statement credit.

Abstract: Disclosed herein are embodiments of hardfacing alloys which can be resistant to hot tearing and cracking. In doing so, the hardfacing alloys can meet certain thermodynamic, microstructural, and performance criteria. For example, embodiments of the alloy have a martensitic matrix embedded with isolated carbides and/or borides. Further, in some embodiments the hardfacing alloys can also have high levels of macro-hardness.

Abstract: An advertised incentive system receives advertised incentive configuration information provided by a merchant. The advertised incentive configuration information defines the content of advertised incentive banners. The advertised incentive banners are provided as needed to merchants to display on the merchant's website. Advertised incentive registration information is received from an account holder after the account holder interacts with the advertised incentive banner. Transaction information is received that contains a qualified purchase made by the account holder. The advertised incentive registration and the qualified purchase are matched. A statement credit is issued against the account holder's account and a debit is issued against the merchant's account in the amount of the statement credit.

Abstract: A refrigeration system for cooling a refrigeration compartment. The refrigeration system comprises a cooling reservoir for cooling refrigerant in a first loop using energy recovered from an engine exhaust stream and a refrigeration circuit comprising a compressor drivable by an internal combustion motor, the compressor circulating refrigerant in a second loop. The refrigeration system comprises at least one heat exchanger in communication with the first and second loops to receive cooled refrigerant, and at least one blower for forcing air over the at least one heat exchanger. A controller selectively activates the internal combustion motor based on a temperature of the cooling reservoir.

Abstract: A pad for a railway rail fastening assembly, the pad being configured for placement between a rail and an underlying foundation, such as slab track or a sleeper, wherein a cross-section of the pad comprises: a second resilient layer configured to face a railway rail; an intermediate rigid layer; and a first resilient layer configured to face an underlying foundation. The rigid layer is provided between and is integrally formed with the first and second resilient layers. An edge of the pad comprises at least one ear that extends beyond a central region of the pad, the rigid layer extending into the ear with the ear being configured to resist rail roll.

Abstract: A navigation and location system is provided that can include an inertial measurement unit (IMU) comprising an in a strap down configuration and a global positioning system (GPS), and a control section that determines orientation of a range sensor aligned with one axis of the IMU with respect to the Earth based on a sequence of system orientation and location measurements from said IMU/GPS along a displaced path from a starting point (SP) to an activation point (AP). Remote geo-location of the object can be determined based on determined range and bearing to the object determined by rotating axis of at least one reference frame from the strap down IMU axis with gravity and aligning another axis with a line of longitude through the displacement path to determine true north then determining a azimuth or bearing angle between true north and the range sensor output axis oriented on the object.

Abstract: A system determines an object-design for a three-dimensional model of an object. The object-design may exhibit a design continuity. The system breaks the object-design in to spatial patterns corresponding to the discrete surfaces making up the outward surface of the object. The system then generates flattened patterns by projecting the spatial patterns into a two-dimensional plane. The system prints the flattened patterns on to designated regions of material sheets in an orientation that preserves the design continuity of the object-design. The regions may be extracted from the sheets and then joined at their edges to form a cover for object that exhibits the continuity of the object design.

Abstract: The present invention relates to compounds and their uses, in particular, compounds in the form of prodrugs that promote transport of a pharmaceutical agent to the lymphatic system and subsequently enhance release of the parent drug.
