Abstract: In one embodiment, the present disclosure is directed to a system for digital authentication. A device includes a second processor for security functionality. The second processor generates a public key and a private key, and uses the private key and to-be-signed signature data to generate digital signatures. The device transmits the public key and a first digital signature to the server. As part of subsequent communication, the device transmits the public key and a second digital signature to the server. Using the public key, the server validates the second digital signature to verify that the second digital signature is from the device or a user of the device, thereby verifying that the subsequent communication is from the device or the user of the device.

Abstract: A fire suppression sprinkler defrosting assembly and system for providing antifreeze to an antifreeze loop includes a bucket containing a fluid comprising an antifreeze solution. A tubing is coupled to the bucket and is in fluid communication with an interior of the bucket, wherein the fluid is passable through the tubing. A valve is coupled to the tubing and is positionable from a closed position to an open position, wherein the valve permits flow of the fluid through the tubing. A pump is coupled to the tubing and is in fluid communication with the interior of the bucket, wherein the pump is actuated to pump the fluid out from the bucket through the tubing when the valve is positioned to the open position. The pump is in fluid communication with an antifreeze loop, wherein the antifreeze solution is provided to the antifreeze loop when the pump is actuated.

Abstract: In one embodiment, the present disclosure is directed to a system for digital authentication, the system including a server and a device. The device includes a first processor and a second processor separate and distinct from the first processor and dedicated solely to security functionality. The second processor is programmed to generate a public key and a private key, and to use the private key and to-be-signed signature data to generate digital signatures, including a first digital signature. The device transmits the public key and the first digital signature to the server. The server stores the public key to uniquely identify the device or a user of the device in subsequent communications between the server and device.

Abstract: An economized refrigeration system includes a main refrigerant circuit having a condenser, an evaporator, an economizer, an expansion device intermediate the condenser and the economizer, and a main compressor fluidly connected by a main refrigerant line. The system also includes an economized refrigerant circuit including an auxiliary compressor system and an auxiliary refrigerant line fluidly connecting the economizer to the auxiliary compressor system and fluidly connecting the main refrigerant line to the auxiliary compressor at a location intermediate the main compressor system and the condenser. The auxiliary compressor system is independently controllable with respect to the main compressor system.

Abstract: Tip-grouting tools may include at least one inlet, an outlet in communication with the at least one inlet, and a distribution material defining a tortuous path between the at least one inlet and the outlet. The distribution material may be configured to distribute at least one of pressure, mass, and flow of grouting material across the outlet.

Abstract: A packaging system for a corrugated cardboard shipping container. The system uses two vertical compartmented inserts divided by a horizontal insert. The compartmented insert can be configured by a packer to consist of four to two rectangular compartments. The horizontal insert can be folded in half or have a quarter section folded away in order to accommodate a loading plan that requires items to protrude above the height of the bottom vertical compartmented insert. An optional diagonal divider and dunnage may be used prior to sealing the container.

Abstract: Systems and methods are disclosed for notifying external message centers when a mobile device becomes available to receive a text message. One embodiment includes a message waiting system that identifies a failed delivery attempt of a text message to a mobile device that is unavailable, where the text message originated from an external message center. The system identifies routing information for the external message center based on the failed delivery attempt, generates a Message Waiting Indicator (MWI) record for the text message that includes the routing information for the external message center, and stores the MWI record. When the system identifies that the mobile device becomes available, the system identifies the MWI record that includes information on the failed delivery attempt to the mobile device, and sends a notification indicating that the mobile device is available to the external message center based on the routing information in the MWI record.

Abstract: Skateboard speed control is achieved by improved application of a mechanism to provide even force to the wheels by a simplified speed control system. The speed control system is durable, compact, simple, uses minimal components, is ergonomic, and has speed control pads that move in sync while simultaneously tolerating variations in wheel orientation and position while a rider is maneuvering the skateboard.

Abstract: A lower deck container for loading onto an aircraft has compartments for receiving one or more items of passenger luggage, for example a conventional suitcase. The compartment include opposing support surfaces spaced from one another so that an item of luggage to be stored in the compartments may span between said support surfaces. The spacing is configured for permitting the passage of a conveyor device which is used loading and unloading operations. Hence, the compartments define a vertical pathway for the passage of a loading/unloading device between the support surfaces (FIG. 2).
