Publication number: 20220296347Abstract: A toothbrush having one or more light sources with an electronic interlock control device preventing operation of the light source when the toothbrush is removed from the user's mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of about 400 nm to about 1000 nm. The light-emitting toothbrush activates upon entering the user's mouth but deactivates immediately when removed, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush head.Type: ApplicationFiled: June 1, 2022Publication date: September 22, 2022Applicant: OraLucent, LLCInventors: Mike Barnes, Timothy Lawrence, Greg Shepherd, Mathieu Julien Jean Emile Zastawny

Publication number: 20220273408Abstract: An electric toothbrush includes a handle with a motor and a light source located in a proximal end. A brush head is in a distal end of the toothbrush, and a drive shaft conveys kinetic energy from the motor to the brush head. The drive shaft includes a light guide from the light source to the distal end and contains two layers of an optical medium of differing refractive indices to enable TIR within the light guide. The brush has a tuft plate having bristles and is made of a polymer such that the water contact angle of the tuft plate is less than 90 degrees and is at least partially transparent. The handle and the tuft plate have electrical contacts to make a contact sensor and a movement sensor provides movement data. A computing device processes movement and contact data to determine when to activate the light.Type: ApplicationFiled: August 19, 2020Publication date: September 1, 2022Applicant: Oralucent, Inc.Inventors: Timothy Lawrence, Greg Shepherd

Publication number: 20170020277Abstract: A short wavelength visible light-emitting toothbrush with an electronic interlock control device preventing operation when the toothbrush is removed from the user's mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of 400 nm to 500 nm. The light-emitting toothbrush activates upon entering the user's mouth but deactivates immediately when removed, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush head.Type: ApplicationFiled: June 2, 2016Publication date: January 26, 2017Applicant: OraLucent, LLCInventors: Mike Barnes, Timothy Lawrence, Greg Shepherd, Mathieu Julien Jean Emile Zastawny, Thomas Jason Dooley

Patent number: 9439503Abstract: A short wavelength visible light-emitting toothbrush with an electronic interlock control device preventing operation when the toothbrush is removed from the user's mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of 400 nm to 500 nm. The light-emitting toothbrush activates upon formation of an electrical circuit between the brush handle in contact with the users hand and the brush head or brush bristles in contact with moisture contained in a human mouth such as saliva or water mixed with toothpaste but deactivates immediately when removed from the mouth, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush-head.Type: GrantFiled: November 20, 2015Date of Patent: September 13, 2016Assignee: OraLucent, LLCInventors: Mike Barnes, Timothy Lawrence, Greg Shepherd, Mathieu Julien Jean Emile Zastawny, Thomas Jason Dooley

Patent number: 9344357Abstract: Techniques are disclosed for aggregating label-switched paths (LPSs). One method for aggregating LSPs may include a first node comparing forwarding equivalence classes (FECs) associated with respective label-switched paths (LSPs). The first node identifies FECs that differ by a given number of bits, such as one or two bits based on the comparison. The first node generates an aggregate FEC that masks out the differing bits, thereby reducing the number of LSPs. The first node transmits the aggregate FEC to an ingress node.Type: GrantFiled: January 24, 2014Date of Patent: May 17, 2016Assignee: Cisco Technology, Inc.Inventors: Ijsbrand Wijnands, Greg Shepherd, Christian Martin, Rajiv Asati
