A sensing baseball game apparatus (10) has a game machine (12) connected to a television monitor (18). A bat input device (32) is provided with an acceleration sensor. An acceleration signal is transmitted by an infrared-ray LED (34) to an infrared-ray receiving part of the game machine (12) whereby the game machine (12) determines a moving speed of the bat input device (32) to calculate a moving parameter of a ball to be batted. Accordingly, a batted ball is moved in the game scene according to the parameter.

Methods and devices are provided for activating brown adipose tissue (BAT). Generally, the methods and devices can activate BAT to increase thermogenesis, e.g., increase heat production in the patient, which over time can lead to weight loss. In one embodiment, a medical device is provided that activates BAT by electrically stimulating nerves that activate the BAT and/or electrically stimulating brown adipocytes directly, thereby increasing thermogenesis in the BAT and inducing weight loss through energy expenditure.

A ball-hitting portion is integrally coated with an elastic body, and thus a bat with durability that can carry the ball far can be obtained. The baseball or softball bat includes a tip portion, a ball-hitting portion, a tapered portion and a grip portion. A depression in the ball-hitting portion is integrally coated with the elastic body having a high rebound property value as a physical property. Thus, when hitting the ball, the elastic body will be compressed and deform, and energy loss due to the ball deformation will be suppressed. Moreover, the ball is carried additionally with a restoring force of the elastic body. Consequently, the bat has rebound property superior to a conventional one, and can carry the ball farther.

An electric powered vehicle is equipped with a main battery for storing electric power input to and output from a motor, and an auxiliary battery as a power source for an auxiliary system including a control system. A DC/DC converter converts an output voltage of the main battery to a level of an output voltage of the auxiliary battery. During operation, a BAT-ECU monitors states of charge of the main battery and the auxiliary battery and controls operation/stop of the DC/DC converter. When the electric powered vehicle is in a key-off state (running stop state), the BAT-ECU is intermittently operated, while an external charging system and a vehicle running system are stopped.

The light tube also formed with two extended axis having a plurality of teeth formed thereon so as to provide the light tube having capability of angle adjustment about the axis of the light tube.

The invention provides a method for determining an optimal route of the airway of an unmanned aerial vehicle. According to the method, the threat of an operation area is more sufficiently considered, more efficient global searching ability is achieved and a more accurate flying route is provided for the unmanned aerial vehicle. The method comprises the following steps: by adopting a quantum encoding mode, changing the state of a basic quantum bit by using a quantum rotating gate and a quantum not-gate, and further updating the position of a bat individual. Because of the diversity of the quantum state, a quantum bat algorithm (QBA) is relatively high in global searching ability and an available or even optimal route avoiding the threat and limiting conditions can be found for the unmanned aerial vehicle. The experiment result shows that the quantum bat algorithm is an effective and stable method for solving the airway route planning problem of the unmanned aerial vehicle, and the search performance of the quantum bat algorithm is superior to that of other swarm intelligence algorithms.

A system, method and computer program product for measuring batted ball performance, including measuring bat and ball speeds using two or more speed measuring devices; and determining elevation and azimuth of a batted ball using a target backstop with elevation and azimuth markings.

A method for analyzing sensor data from baseball swings (or swings in similar sports) that transforms data into a reference frame defined by the bat orientation and velocity at impact. The trajectory of the sweet spot of the bat is tracked through the swing, and is analyzed to generate metrics describing the swing. A two-lever model of the swing may be used to model the effects of body rotation and wrist rotation. Data may be analyzed to identify relevant events during the swing such as start of downswing, commit (wrist release), on-plane, peak bat speed, and impact. Illustrative swing metrics derived from the sweet spot trajectory, the swing plane reference frame, and the two-lever model include: forward bat speed, on-plane rotation, hinge angle at commit, hinge angle at impact, body rotation ratio, body tilt angle, and swing plane tilt angle.

A metal baseball or softball bat may be improved both for durability and performance by selectively placing a layer of polymer material around portions of the bat. In one embodiment, the barrel portion of the bat may have a polymer layer directly laid up upon the metal bat frame. In a second embodiment, the barrel portion of the bat may include an outer metal sleeve placed about the metal bat frame, with an exterior polymer shell being formed on the outer metal sleeve. In a third embodiment, an intermediate portion of the bat adjacent a zone of maximum bending stress may be reinforced by the placement of a polymer outer layer on the metal frame of the bat adjacent the area of maximum bending stress.

A bat includes a composite material barrel. The barrel includes a plurality of layers. A stiffening layer forms one of the exterior layers of the barrel. The stiffening layer includes unidirectional fibers, where the unidirectional fibers are oriented to substantially encircle the barrel. The stiffening layer is positioned on the barrel to cover at least a portion of the sweet zone. The barrel may include multiple walls, where each wall includes a stiffening layer.

A single member tubular baseball or softball bat of unitary construction comprised of an elongated handle portion and a striking or barrel portion wherein the barrel portion has internal and external cylindrical layers separated by one or more separation barriers, which are not bonded to said layers, located internally within the barrel thickness, and being in intimate contact with these layers. This results in equivalent or higher performing baseball bats than the prior art, as measured by hitting distance, and more consistent performance. The bats are also less costly to manufacture than prior art double walled bats.
