Patent number: 11464312Abstract: A hair care device comprises a body having an output to supply heated air, and at least two different attachments that can be attached to the output of the body. In accordance with the invention, the body comprises a detector for detecting whether one of the attachments is attached to the body, and if so, which attachment is attached to the body, to provide a detection result, and a controller for controlling the supply of heated air in dependence on the detection result. According to the invention, each attachment has at least one magnet at predefined positions at an attachment contact area of the attachment for contacting the body, the at least two attachments having mutually different magnet configurations, and the detector comprises a plurality of Hall effect sensors at predefined positions (?) at a body contact area for contacting a selected one of the attachments.Type: GrantFiled: June 8, 2018Date of Patent: October 11, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Chuen Yu Cyrus Pang, Cho Woo, Wing-Hei Cho

Patent number: 10383422Abstract: An air outlet grill for use on a hair care device comprises a plurality of concentric and tilted flow guide surfaces (2), a cross section of the flow guide surfaces (2) having a curved shape that diverges in an air flow direction. Preferably, tilt angles between the flow guide surfaces (2) are designed such that an air inlet area of the air outlet grill is larger than an air outlet area of the air outlet grill, so as to increase air speed. Preferably, a middle flow guide surface has a smaller height compared to at least one other flow guide surface, so as to increase an area for air to pass through at a middle part of the air outlet grill. Preferably, a leading edge of at least one of the flow guide surfaces (2) is tangent to the air flow direction while a trailing edge of the flow guide surfaces diverges from the air flow direction.Type: GrantFiled: July 12, 2016Date of Patent: August 20, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Chak Yuen Law, Cho Woo

Patent number: 7356451Abstract: Disclosed is a method and system for handling timing constraints or assertions for timing model extraction. One disclosed approach for assertion handling is by automatically preserving the integrity of original assertions by retaining existing pins or creating new internal pins. The assertions are viewed as part of the model, and a set of new assertions are generated automatically as part of the timing model extraction process and can be stored as part of the model. Assertions can be associated with input ports, output ports, internal pins, or hierarchical pins and can even span multiple blocks. This disclosed approach allows for application of assertions associated with timing models when the model is instantiated and detachment of assertions when the model is de-instantiated, and thus removes one of main problems associated with timing models.Type: GrantFiled: December 6, 2002Date of Patent: April 8, 2008Assignee: Cadence Design Systems, Inc.Inventors: Cho Woo Moon, Harish Kriplani, Krishna Prasad Belkhale

Patent number: 6928630Abstract: Disclosed is a method and system for extracting a timing model. One disclosed approach to extract a timing model is by reducing the timing graph. Original timing behavior is preserved in the timing model including arrival times, slew times, timing violations and even latch time borrowing that is independent of clock waveforms. Also, original timing constraints can be captured in the model and be applied automatically when the model is used. Anchor points are automatically identified and retained to obtain a model that is smaller than the original netlist.Type: GrantFiled: December 6, 2002Date of Patent: August 9, 2005Assignee: Cadence Design Systems, Inc.Inventors: Cho Woo Moon, Harish Kriplani, Krishna Prasad Belkhale
