Abstract: A method for pooling and retrieving block rewards in a reward pool including an operator node and a set of member nodes in a distributed network extending a proof-of-space-based blockchain includes: submitting a transaction configured to generate a singleton in a set of singletons, the singleton including: an outer puzzle hash linking the singleton to a singleton puzzle hash; and an inner puzzle hash defining a pool address associated with the reward pool; generating a block including a proof-of-space and a block reward allocated to the singleton puzzle hash; detecting the block reward allocated to the singleton puzzle hash; identifying the singleton linked to the singleton puzzle hash; and submitting a transaction configured to: remove the singleton from the set of singletons; and transfer the block reward from the singleton puzzle hash to the pool address.

Abstract: A friction pad (12) for inhibiting movement of a device (10) relative to an engagement surface (16) includes a pad body (18) and an adhesive material (232). The pad body (18) has a first body surface (20) and an opposed second body surface (22). The first body surface (20) is configured to be coupled to an outer surface (14) of the device (10). The second body surface (22) is configured to engage the engagement surface (16). The pad body (18) is formed at least in part from a body material (18A) including high-density polyethylene. The second body surface (22) of the pad body (18) has a static coefficient of friction of at least approximately 1.0. The second body surface (22) includes a plurality of spaced apart surface features (234), each of the plurality of surface features (234) having a feature height (358) of between approximately 0.15 millimeters and 1.00 millimeters.

Abstract: A friction pad (12) for inhibiting movement of a device (10), e.g., a portable electronic device, relative to an engagement surface (16) includes a pad body (18) having a first body surface (20) and an opposed second body surface (22). The first body surface (20) is configured to be coupled to an outer surface (14) of the portable electronic device (10), and the second body surface (22) is configured to engage the engagement surface (16). The pad body (18) is formed at least in part from a body material (18A) including high-density polyethylene. Additionally, the second body surface (22) of the pad body (18) has a static coefficient of friction of at least approximately 0.60.

Abstract: Liquid tank measuring systems that weigh/measure the amount of liquid in a fixed tank/vessel are disclosed. Also disclosed are methods that provide load cell failure detection of the liquid tank measuring system and the ability to continue operations post load cell failure detection.

Abstract: A system and method of removably attaching a flooring surface material to a subfloor. The subfloor may include a modular raised flooring system comprising a plurality of raised floor panels, and comprising a magnetic body, surface or underlayment material. The flooring surface material includes a magnetic attachment surface that holds the flooring surface material in place on the subfloor by magnetic attraction, but that allows removal for disassembly and/or replacement.

Abstract: A web based Assessment Center system that imposes a prescribed workflow and facilitates defined interactions between the various participants implementing the Assessment Center method using portal technology. The system relies on a hub-and-spoke web-based client/server architecture, and a software foundation comprising an open-architecture modular array of web-based software for data collection and exchange between the various participants. The software modules include a Role profile module by which a customer can specify a freeform customer role profile, a Job Analysis module for distilling suitability ranking factors from the customer's free form Role profile, a Proctor Module for online testing, a Simulation Module for recording video simulations, and a Scoring Module for standardizing multiple Assessor scoring of the recorded video simulations and consolidation of the online test scores and simulation scores into a Data Map for collective decision-making.
