The power conversion of the input power to the output power may be controlled to maximize the input power by setting at the input terminals the input voltage or the input current according to predetermined criteria. One of the predetermined criteria is configured to reduce the input power based on the temperature signal responsive to the temperature. The adjustment of input power reduces the input voltage and/or input current thereby lowering the temperature of the power converter. | 08-21-2014 |

| 20160001453 | ELECTRIC SHAVER WITH IMAGING CAPABILITY - System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver. | 01-07-2016 |
| 20160028695 | SYSTEM AND METHOD FOR ROUTING-BASED INTERNET SECURITY - Method and system for improving the security of storing digital data in a memory or its delivery as a message over the Internet from a sender to a receiver using one or more hops is disclosed. The message is split at the sender into multiple overlapping or non-overlapping slices according to a slicing scheme, and the slices are encapsulated in packets each destined to a different relay server as an intermediate node according to a delivery scheme. The relay servers relay the received slices to another other relay server or to the receiver. Upon receiving all the packets containing all the slices, the receiver combines the slices reversing the slicing scheme, whereby reconstructing the message sent. | 01-28-2016 |

| 20160114221 | System and Method for a Motion Sensing Device which Provides a Visual or Audible Indication - A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed. | 04-28-2016 |
