Abstract: A work-piece securing apparatus for metal or wood working equipment, for example a miter saw, involves a support element mounted on the equipment and an elongated work-piece securing element movably supported by the support element. The support element is configured to receive and support the securing element such that the securing element retains mobility while supported on the support element to permit manual manipulation of the securing element to position the work-piece on the equipment and/or to position a work-piece engaging portion of the securing element at a desired contact point on a work-piece when the work-piece is positioned to be worked by a tool of the equipment.

Abstract: A water heater apparatus includes an elongated radial burner extending along a longitudinal central axis of the apparatus. First and second concentric rows of longitudinally extending fin tubes around the radial burner. The fin tubes may have multiple wiped circumferentially laterally portions allowing close packing of the fin tubes for improved efficiency and reduced footprint.

Abstract: Systems, methods, and computer-readable media are provided for graph data modeling. In accordance with one implementation, a method is provided that includes operations performed by at least one processor. The operations of the method include receiving raw data and determining a model for the raw data, wherein the model defines the graph structure for the raw data. The method also includes converting the raw data to fit the model, and generating at least a portion of a graph based on the raw data and the model, wherein the graph produces modeled data. The method also includes archiving the graph.

Abstract: Persuasive technologies aim to influence user's behaviors. In order to be effective, many of the persuasive technologies developed so far relies on user's motivation and ability, which is highly variable and often the reason behind the failure of such technology. Mindless Computing, a new approach to persuasive technology design, is presented. Mindless Computing leverages theories and concepts from psychology and behavioral economics into the design of technologies for behavior change. Most of the current persuasive technologies do not utilize the fast and automatic mental processes for behavioral change and there is an opportunity for persuasive technology designers to develop systems that are less reliant on user's motivation and ability.

Abstract: A pre-mix burner apparatus includes a burner having a generally cylindrical burner surface, the burner having a generally circular burner inlet at one end of the burner, the burner inlet having an inlet diameter. A flow distribution member is arranged to distribute flow of fuel and air mixture into the burner. The flow distribution member includes a closed axially central portion configured to block flow of fuel and air mixture axially centrally into the burner. The flow distribution member includes a plurality of vanes extending radially outward from the closed axially central portion. The vanes are configured to generate a swirling flow of fuel and air mixture flowing past the vanes into the burner.

Abstract: Methods, systems, and devices are disclosed for implementing mobile sensing of non-speech sounds from a human. In one aspect, a mobile sensing system includes a microphone to capture a diverse set of body sounds while dampening external sounds and ambient noises, wherein the captured diverse set of body sounds are not speech. The mobile sensing system includes a micro-controller in communication with the microphone to perform an algorithm for signal processing and machine learning using the captured diverse set of body sounds.

Abstract: Systems and methods are disclosed for managing electronic content, such as over the Internet. One computer-implemented method for managing electronic content includes: receiving, over an electronic network, log data of activities by Internet users; filtering the log data based on at least one aspect of the activities; aggregating the filtered log data by a predetermined period of time; calculating a trend in the aggregated log data based on a change of the activities; and presenting a request to a contributor over the electronic network, the request soliciting the submission of electronic content relating to the calculated trend.
