20100145143 | VIBRATING ROBOTIC CRAWLER - An autonomous vibration-driven device, for motion through a lumen or along a surface, utilizing an array of flexible fibers attached to the body of the device. The outer surface of the fibers have an anisotropic coefficient of friction with the surface along which the device is to move, and the fibers extend from the device body such that at least some of the fibers are in contact with the walls along a part of their length. A transducer is used to vibrate the device, such that it moves down the lumen. The transducer can be either device borne or external. A rotary device is also described, utilizing an array of fibers disposed on the rotor's body, the fibers having an anisotropic coefficient of friction with a central stator or with an outer circular wall. A planar motion device is also described for crawling over a planar surface. | 06-10-2010 |
20150047452 | ROBOTIC MECHANISM WITH TWO DEGREES OF FREEDOM - A robotic link mechanism comprising a pair of base elements connected by a passive flexible joint, such that flexure of the joint changes the mutual orientation of the base elements. A pair of obliquely truncated cylinders are confined between the base elements such that the obliquely formed end surfaces of the cylinders can rotate in sliding contact with each other, and the other end of each cylinder can rotate in sliding contact with its associated base element. Driving motors are attached to the base elements, each one controlled to rotate the cylinder associated with that base element, such that rotation of at least one of the cylinders causes the base elements to undergo change in their mutual orientation. The mechanism thus has a backbone composed of the passive flexible joint, which is supported and actuated by the oblique truncated cylindrical structure that serves as an active exoskeleton. | 02-19-2015 |

20080219359 | Method and system for reducing common mode noise interference in a differential communication channel - A data transmission method includes providing, by a current source, a current to the first conductor while isolating the second conductor from the current source, to thereby transmit a first binary digit; and, responsive to a command to transmit a second binary digit, (i) decreasing from a maximum value to zero an amount of the current provided to the first conductor and (ii) increasing from zero to a maximum value an amount of the current provided by the current source to the second conductor. The decreasing and the increasing are performed simultaneously, in such a manner that the amount of the current provided to the first conductor decreases at the same rate as the amount of the current provided to the second conductor increases, and such that each of a first signal corresponding to the current provided to the first conductor and a second signal corresponding to the current provided to the second conductor has a transition edge having a leading section, a midsection and a trailing section, with the midsection of the transition edge having an average slope that is greater than an average slope of the leading section of the transition edge and that is greater than an average slope of the trailing section of the transition edge. A system is provided which includes a switching system, which is operatively interposed between the current source and the differential communication channel, and a controller which is operative to issue one or more signals control signals to the switching system to implement the data transmission method. | 09-11-2008 |
20080288714 | FILE STORAGE IN A COMPUTER SYSTEM WITH DIVERSE STORAGE MEDIA - A method for storing data in a computer having a magnetic hard disk drive (HDD) and an electronic solid-state drive (SSD). The method includes configuring the computer so that the HDD and the SSD are each independently accessible by an operating system of the computer. A plurality of files is received for storage by the computer. A predicted use profile of the computer is defined. A respective one of the HDD and the SDD is selected for the storage of each of the files responsively to the predicted use profile. | 11-20-2008 |
20080299834 | BACK-TO-BACK PCB USB CONNECTOR - A double-sided USB connector may include a first PCB that may provide a first set of electrical contacts on its first side and solder pads on its second side. The first PCB may further include a components side, solder pads, and signal traces. The double-sided USB connector may also include a second PCB that may provide a second set of electrical contacts on its first side and terminals on its second side. Contacts selected from the second set of contacts may be connected to selected terminals, for example through via paths in the second PCB. Contacts from the first and second sets of contacts may selectively be connected to components on the first PCB using signal traces rather than wires. The first PCB may be joined to the second PCB by using the terminals, and the two PCBs may be packaged using a common molded body. | 12-04-2008 |
20140189280 | Reuse of Host Hibernation Storage Space By Memory Controller - A method for data storage includes, in a host system that operates alternately in a normal state and a hibernation state, reserving a hibernation storage space in a non-volatile storage device for storage of hibernation-related information in preparation for entering the hibernation state. While the host system is operating in the normal state, a storage task other than storage of the hibernation-related information is performed using at least a portion of the reserved hibernation storage space. | 07-03-2014 |
20150208488 | ADAPTING TURN SIGNAL - A vehicle operator may activate turn signals without interfering with his/her enjoyment of ambient music. A turn signal system has a tempo extractor to determine the tempo of the ambient music and a trigger generator to transmit to a turn signal controller a trigger that causes the system's turn signaling mechanism to produce a repetitive sound that coincides with the ambient music. As the repetitive sound does not interfere with the vehicle operator's music enjoyment, the system increases diligence in the use of turn signals and thus increases safety of the vehicle operator and the safety of those proximate the vehicle operator who would be affected by a vehicle turn or lane change. | 07-23-2015 |
