Abstract: A golf club head of the wood-type, including a body having a ball-striking face and a sole, is disclosed. The sole can include a wave slot for adding additional weight to the golf club head and for providing improved performance. The wave slot can include a front sidewall, a rear sidewall, and at least two waves. The waves can be positioned between the front and rear sidewalls and can each include a valley portion at the lowest point of the wave such that the valley portion does not protrude below the sole.

Abstract: There is provided inter alia polypeptides such as antibodies or fragments thereof which bind to LPAR1.

Abstract: A bat, which has a hollow barrel and an internal assembly configured to resist deformation of the hollow barrel, is disclosed. The internal assembly includes a rod disposed longitudinally in the hollow barrel, a ring attached to the rod, a deformable sleeve disposed around the ring and extending longitudinally in the hollow barrel. The sleeve can include an outer diameter smaller than an inner diameter of the hollow barrel. The bat can include an end cap attached to an end of the hollow barrel and having a recess configured to receive an end of the rod. The rod can be configured to maintain the deformable sleeve in a predetermined suspended position within the hollow barrel such that, when the bat is at rest, the sleeve is disposed a predetermined gap distance from an inner surface of the hollow barrel.

Abstract: A bat, which has a hollow barrel and an internal assembly configured to resist deformation of the hollow barrel, is disclosed. The internal assembly includes multiple rods disposed longitudinally within the hollow barrel. The internal assembly can include a deformable ring having a substantially circular outer wall having a diameter less than an inner diameter of the hollow barrel and multiple holes, with each hole configured to at least partially receive a rod of the multiple rods. The bat can have an end cap including end cap holes extending partially through the end cap, with each end cap hole configured to at least partially receive a rod.

The sole can include a wave slot for adding additional weight to the golf club head and for providing improved performance. The wave slot can include a front sidewall, a rear sidewall, and at least two waves. The wave slot can be open-ended. The waves can be positioned between the front and rear sidewalls and can each include a valley portion at the lowest point of the wave such that the valley portion does not protrude below the sole. The wave slot can also have two, three, or more waves, which can have heights that decrease as the position of the waves increases with respect to the ball-striking face.

Abstract: Various improvements are provided to resonant DC/DC and AC/DC converter circuit. The improvements are of particular interest for LLC circuits. Some examples relate to self-oscillating circuit and others relate to converter circuits with frequency control, for example for power factor correction, driven by an oscillator.

Abstract: An AC/DC PFC converter comprises an LLC PFC pre-regulator and a DC/DC converter output stage. The output stage has a feedback unit adapted to provide a feedback signal (in addition to the conventional feedback of the bus voltage error) to the control circuit of the PFC pre-regulator for modulating the controlled output voltage of the PFC pre-regulator in dependence on the output power and/or the input current and voltage. In this way, the total harmonic distortion of the input of the converter can be reduced by controlling the gate switching in the PFC pre-regulator.

Abstract: A half bridge resonant converter comprises a half bridge inverter having a high side switch and a low side switch with an output defined from a node between the high side switch and the low side switch. The output connects to a resonant circuit. There are separate control circuits for generating the gate drive signals for controlling the switching of the high side switch and low side switch, in dependence on an electrical feedback parameter, each with different reference voltage supplies.
