A golf club head having portions of varying density is disclosed and claimed. The club head includes a body with a recess in the back between the heel and toe and extending toward the sole. An insert that is configured to matingly correspond to the recess is positioned within the recess. The insert has a lower specific gravity than the club head body, biasing the club head mass toward the club head perimeter. The insert can form a muscle of the club head. The club head is forged, and the recess is formed by machining. After the insert is positioned within the recess, the club head-insert combination is subjected to additional forging and finishing steps. The present invention increases the club head moment of inertia and / or enlarges the club head sweet spot while retaining the golfer's ability to work the golf ball and shape the golf shot. The present invention can be used with forged, blade, and muscle back clubs, which have not heretofore been enhanced in these manners.

The small unmanned ground robot has the advantages that the traveling drive mechanism of the robot adopts a track mode to increase the adhesive force with the ground; track wheels adopt the design of absorbing energy and vibration to improve the capacity of collision resistance of the robot; detachable front auxiliary wheels adopt a track structure to improve trafficability performance of the robot, and have the functions of assisting spanning entrenchments and obstacles, assisting climbing stairs, and rotating and turning over; mechanical arms adopt six freedom of motion, have the characteristics of flexibility, convenience, reliability, strong working capability, and the like, and can grab and carry objects; the robot adopts the design of no exposed skinned wires and water resistance and can work all day long; and the traveling drive mechanism can walk in water.

One embodiment disclosed relates to a method of compiling a computer program. A plurality of modules of source code is received, and intermediate representations corresponding to the modules are generated. A set of data from the intermediate representations is extracted to create an inliner summary for each module. Using the inliner summaries and a globally-sorted working-list based order, an inline analysis phase determines which call sites in the modules are to be inlined by substituting code from a called module. The propagation of summaries may be done elaborately, potentially throughout the call-graph. The goodness of call sites may be computed with a view to comparing them and ordering them in a descending order of goodness. Applicants believe the compile-time effectiveness lies in the ability to work consistently with summary information in the inline analysis phase without having to touch the intermediate representation, while maintaining a high degree of run-time performance by continuously updating the summary information.

A system of radio frequency communication between Readers and Tags, the system comprising at least one tag Reader and a plurality of Tags, each tag is given a unique tag ID, deployed in a region in which at least some of the Tags are in radio communication with the tag Reader and a Media Access Control protocol such that the tag Reader is configured to send and receive radio communication to and from at least some of the plurality of Tags. The plurality of Tags are configured to send and receive radio communication to and from the tag Reader and the Media Access Control protocol is configured to control the radio communication between the tag Reader and the plurality of Tags The Media Access Control protocol includes a multi-dimensional addressing scheme allowing Readers to efficiently address tag communities ranging from small to very large in unicast, multicast and broadcast modes. The multi-dimensional addressing scheme enables division of the plurality of Tags into a number of groups for different stages of Media Access Control protocol processing, based on different portions of the tag ID. A hash function is used to transform the tag ID into a pseudo random ID, so as to achieve better spreading of tag population and lower statistical dependency between dimensions. The MAC has an inherent flexibility in the sense that it allows readers to communicate with different versions of tags and also to optimize communication parameters to reader's capabilities, without pre-configuration of the tags. Furthermore, the MAC supports means to achieve very high access reliability, such as relay between tags, and the ability to work with tags that alternate between active and sleep mode) including means for power savings. All of these novel features, coupled with some prior art concepts like collision resolution algorithms, result in a scalable MAC protocol for an active RFID system employing multiple access.

A system and method for advanced digital economization for an HVAC system having an economizer. A digital processing unit is configured to open a damper of an economizer within a dead-band range that allows for preemptive cooling prior to a call for cooling. This economization strategy allows for free cooling (outside air) without having to pay energy costs for cooled (air-conditioned) air. The system and method can be used with or without demand control ventilation (DCV). The method also includes a “self-learning” strategy with outside air and return air sensor to regularly sense past economizer damper modifications and average out recent readings to help set the dead-band range. The method can include the ability to work in conjunction with a variable supply fan speed control, provide fault detection, self-correct, auto-configure, and report system status.

A pair of conditioning rolls is disclosed that comprise one steel and one rubber / urethane roll. The steel roll has raised ribs formed thereon or attached thereto in a spiral configuration, while the rubber / urethane roll contains grooves therein that intermesh with the raised ribs during operation to grip the crop material. The smooth areas of the rolls crush the crop stems. Alternative embodiments of the grooves provide the ability to work within a wide range of crops, including crops that have heretofore proven difficult to condition.

An advanced image intensifier assembly provides enhanced functionality. A grounded photocathode provides shielding from electromagnetic interference, improving the ability to work in multiple light conditions. Bi-directional wireless communication and non-volatile storage allow critical information to be permanently stored and read wirelessly at a scanning station, easing in identification of units. Because bi-directional communication components can be embedded within an image intensifier assembly, existing end-user night vision devices can be upgraded by simply replacing the image intensifier assembly. For enhanced safety, a programmable shutdown capability is provided. This renders the device inoperative in the absence of continuous input, either wireless or manual, from an authorized operator, thus rendering the device useless if captured by enemy combatants. Finally, direct 1-volt operation enables the device to be powered by, for example, a single AA battery.

Provided is a lightening protection internet of things survivability optimization method based on a complex network. An optimization design is conducted towards a network topology structure so that important businesses are not affected when the network breaks down. The method is to add a backup link and a backup device to the network and the number of the backup is more than enough. With an adding of the number of nodes or edges to the network, a shortest distance between the nodes can be shortened and a network connectivity is improved so that a working performance can be maintained through other nodes and edges when the network is faced with an attack. Besides, two types of rebuilding connection strategy AIR and AUR are adopted to remove or reconnect a connection between high number and low number nodes according to a presupposed threshold value T. Through optimizing the network topology structure, a communication reliability is enhanced.
