Patent number: 11464202Abstract: A trailer apparatus is provided having two half forms connected to a frame joint, the half forms mounted on a first and second pivot bar on the joint frame to pivot to open and to pivot to close in a clam shell arrangement. The trailer apparatus may assume a form of backpack or luggage piece adapted to store items and may assume the form of a towable trailer, having a tow bar, wheels, and a three-dimensional covering over the open sides of the half forms to enclose cargo space or to keep a pet inside the footprint of the half form adapted as trailer bed when the trailer apparatus is extended for use.Type: GrantFiled: September 22, 2021Date of Patent: October 11, 2022Assignee: Get Waggin Inc.Inventor: Cesar Lopez

Publication number: 20220134293Abstract: Provided are certain polyolefinic membranes which are useful as components of filters for liquid purification. Advantageously, the filter membranes of the disclosure possess greatly reduced concentrations of certain trace metals, thus making them particularly useful in the filtration of liquids used in the fabrication of microelectronic devices. In one aspect, the disclosure provides a filter membrane comprising a polyolefin, wherein said polyolefin has less than about 4 ppm total of metals chosen from titanium, aluminum, iron, zinc, and magnesium.Type: ApplicationFiled: October 27, 2021Publication date: May 5, 2022Inventors: Cesar Lopez Gonzalez, Jad Ali Jaber

Patent number: 10992470Abstract: The invention provides implementations of the block cipher in resource-constrained ARM devices that may be applied to both 32-bit and 64-bit versions of side-channel resistant and vectorized code and provides improves both efficiency and compactness by using of algorithmic techniques and features specific to a target platform. Specifically, an unprotected 32-bit implementation improves speed while reducing code size and a vectorized implementation improves performance and speed the implementation of block cipher.Type: GrantFiled: May 12, 2017Date of Patent: April 27, 2021Assignees: LG Electronics, Inc., UNICAMPInventors: Rafael Junio Da Cruz, Diego F.

Patent number: 10911218Abstract: A method for encrypting data with a provided key. The method includes generating a plurality of keys; processing the data in a plurality of rounds, with each round including: performing a first logical combination of the data with a first key; first permuting the first logically combined data based on a first defined permutation; performing a first substitution on the first permuted data; second permuting the first substituted data based on a second defined permutation; performing a second logical combination of the second permuted data with a permuted second key; and performing a second substitution on the second logically combined data. Further, performing a penultimate logical combination of the second substituted data with a penultimate key, permuting the penultimate logically combined data, performing a final substitution of the permuted data, and performing a final logical combination of the final substituted data with a last key.Type: GrantFiled: September 29, 2017Date of Patent: February 2, 2021Assignees: LG ELECTRONICS INC., UNICAMPInventors: Julio Cesar Lopez Hernandez, Tiago Bruno Silva Dos Reis

Patent number: 6354722Abstract: A vehicle headlight has a cam mechanism for displacing the reflector and the light source of the headlight with respect to each other, between two relative positions in which the headlight emits two different types of light beam. The cam mechanism comprises a first cam member and a second cam member, and it converts rotation of the first cam member about an axis of rotation into a first straight line motion of the second cam member. The first straight line motion is collinear with the axis of rotation.Type: GrantFiled: February 22, 2000Date of Patent: March 12, 2002Assignee: Valeo VisionInventors: Cesar Lopez Montenegro, Jean Paul Ravier
