Title: Systems and methods for estimation of building wall area
Inventor: PERSHING CHRIS
IPC: G06F17/50
Filed: 2013-02-01
Abstract: A wall area estimation system generates an estimated wall area measurement of a building based on the received roof measurements (e.g., those generated by, received from or found in a three-dimensional model of the roof) and a reference distance. The reference distance is a measurement indicative of a distance between the roof and a model ground surface placed on an image of the building where the walls of the building meet the ground. This reference distance may be used to determine how for down to extend the walls of the building (e.g., to a ground level) when building a three-dimensional digital model of the building to aid in generating wall area measurements. The resulting wall measurements, roof measurements, measurements of areas missing from the wall used to generate a wall estimate report, or a combined roof and wall estimate report including various different identifiers indicating the different features and measurements based on the three-dimensional model.

Title: Polyphonic humbucking guitar pickup
Inventor: NICOLAE PONICI
IPC: H04R1/46
Filed: 2014-10-28
Abstract: The polyphonic humbucking guitar pickup transducer comprised of multiple electromagnetic sensors, to capture the sound of each string separately of a musical instrument that uses ferromagnetic strings such as the electric guitar. The pickup works either in passive or active mode, assembled in a humbucking noise cancelling configuration and assembled as industry standard size (single-coil or double-coil guitar pickup). Each signal can be reproduced by an audio amplifier assigned for each string individually or summed in stereophonic or monophonic configuration with a high degree of separation between strings.

Abstract: Techniques for establishing and implementing application-based routing policies for multi-mode wireless communication devices such as a user equipment (UE) are generally described herein. In some examples, information particular to the profile and platform configuration of the UE is communicated to an Access Network Discovery Function (ANDSF) server. The ANDSF server may provide an inter-system routing policy (ISRP) to handle appropriate network offloading actions for the particular application and device configuration. In some examples, the ISRP may be specific to flow-based or non-seamless based traffic offloading from certain software applications. The techniques described herein may be propagated from the ANDSF server and implemented in a variety of multi-mode UE mobile computing devices in connection with offloading policies established in a 3GPP Long Term Evolution/Long Term Evolution-Advanced (LTE/LTE-A) Evolved Packet Core (EPC) network architecture.

Title: Epilation by thermolysis
Inventor: ANDERER SUZANNE
IPC: A61B18/00
Filed: 2015-06-03
Abstract: A method for removing hair by thermolysis is provided. The method steps include oscillating a direct current to create an alternating current ("AC") micro-pulse, pulsing the AC micro-pulse on and off continuously, delivering the AC micro-pulse to a probe, applying the probe to a hair follicle, and inverting the direction of the AC micro-pulse on the hair follicle. When the probe is applied to the hair follicle, the AC micro-pulse travels from the top of the dermis of the hair follicle to a dermal papilla of the hair follicle. The AC micro-pulse reverses direction at the dermal papilla and travels to the top of the dermis of the hair follicle. The AC  micro-pulse produces heat that destroys the tissues controlling the growth of the hair follicle.
