Abstract: A data storage system creates a data signature for a data element that is to be stored by hashing the data element. The data storage system also creates a sequence signature for the data element and stores the sequence signature in a signature database. The sequence signature is created using the data signature of the data element and the previous sequence signature stored in the signature database. The data storage system transmits a copy of the sequence signature to an anchor system. The anchor system stores the copy as an export anchor and creates an import anchor based on the export anchor and information associated with the present time. The anchor system stores the import anchor and transmits a copy to the data storage system. An audit system uses the export anchor and import anchor to determine whether data stored by the data storage system has been modified.

Abstract: A coupling assembly for coupling solar photovoltaic modules together in an array includes a base portion including a base surface for operatively engaging a bottom surface of at least one of the solar photovoltaic modules. The coupling assembly also includes a cap portion including a clamping surface located opposite the base surface for operatively engaging a top surface of at least one of the solar photovoltaic modules. The coupling assembly further includes a spacer slidably mounted to one of the base portion or the cap portion and having first and second abutment sides each configured to operatively engage a side surface of at least one of the solar photovoltaic modules. The base surface and the clamping surface are moveable relative to each other such that movement of the clamping surface toward the base surface provides a clamping action on at least one of the solar photovoltaic modules positioned therebetween.

Abstract: According to the invention, an LED fixture is provided for photographic and theatrical lighting. The light fixture is particularly suitable for photographic and theatrical lighting by mounting LED elements directly or indirectly on articulating arms. The arms rotate 90 degrees from a position where the arms are aligned substantially in parallel with an axis of the fixture hub and may be rotated 90 degrees for deployment of the fixture. In addition, the spokes may be flexed beyond the alignment permitted by the cooperation between the hub and mounting elements.

Abstract: When a user of an interface system defines a workflow, the interface system transmits a notification to a user that is to perform the first step of the workflow. When the user requests to initiate the step of the workflow, the interface system creates a transaction for the workflow step. The user signs the transaction using a cryptographic key pair. The interface system receives the signed transaction and verifies the signature. Once the signature is verified, the step can be performed. The interface system forwards the transaction to a data storage system for storing. For performing the next step in the workflow, the data storage system identifies the user that is to perform the next workflow step. The data storage system creates a notification that identifies the user and the notification is provided to the user. The process repeats until each step of the workflow is performed.

Abstract: A data integrity system generates a transaction signature associated with a transaction based on transaction data received from a data producer. The transaction signature is unique to the transaction and is generated by applying a hash function to the transaction data. When the transaction data is to be transmitted to a data consumer, the data integrity system redacts the transaction data based on permission information associated with the data consumer and transmits the redacted transaction data to the data consumer. To enable the data consumer to verify the integrity of the received data, the data integrity system also transmits a cryptographic assurance that includes at least the transaction signature associated with the transaction. The data consumer verifies the integrity of the received data by independently generating a transaction signature based on the redacted transaction data and matching the independently generated signature with the transaction signature in the cryptographic assurance.

Abstract: A foot rest for a post-hole digger and post-hole diggers using the foot rest are disclosed. The foot rest includes two portions, one attached to each shaft of the post-hole digger. The two portions have structure that allows them to engage one another when the two shafts of the post-hole digger are vertical. The foot rest does not extend beyond the bore diameter of the post-hole digger. Thus, in order to keep the user's feet on the relatively short foot rest, the contact surface of the foot rest may be angled. In some embodiments, the foot rest may be symmetrical, so that either side may be used as the upper surface. A post-hole digger including the foot rests typically includes at least two foot rests, spaced from one another and facing different directions along the shafts of the tool.

Abstract: C. difficile infection (CDI) is the most common cause of antibiotic-associated diarrhea. Unfortunately, antibiotic therapy remains as the standard treatment for this antibiotic-induced disease and relapses are common. Antibiotic treatment typically is given for 10 to 14 days for initial or second episode of CDI. For recurrent episodes, more prolonged courses are recommended. It is disclosed herein that lower dose or shorter course of the antimicrobial treatment is sufficient to treat the disease and prevent recurrent disease by enabling a good immunologic response to infection, and perhaps also by better preserving normal flora, thus protecting against relapses or reinfection.

The logging tool may be releasably latched to the pipe, and may include position sensors for position feedback and depth correction.

Abstract: A quick attachment and release mounting mechanism for a camera. The mechanism includes a clamping base with clamping structure adapted to be secured around an object, such as a paddle, and an adapter. The clamping base includes a receptacle which is trapezoidal and narrower at the top, and also tapers from one end to the other. The receptacle is disclosed forwardly of the clamping structure. The adapter includes a fastener adapted to engage a camera, and a leading portion with a shape that is complementary to that of the receptacle. A latch mechanism is provided to latch the adapter and receptacle together. The latch mechanism is shielded from accidental disengagement by a frame.

Abstract: A sub-surface safety system for hydrocarbon drilling operations is provided and includes at least one casing within a wellbore that extends into a first portion of a formation from the surface of the formation. A shut-in device is positioned in the casing so as to be below the surface of the formation. The well shut-in device defines a device passageway and is operable to sever a drill string extending through the device passageway and form a barrier in the device passageway that restricts wellbore fluids below the barrier from migrating up the casing to the surface.
