Patent number: 9641918Abstract: An audio unit, connected or connectable to a safety-critical apparatus, or integrated or integrable in the apparatus, is proposed. The audio unit may comprise a driver unit, a detection unit, and an alert unit. The driver unit may generate an analog audio signal in response to a request from the apparatus, to drive an acoustic output unit and thereby generate an acoustic signal for a user of the apparatus. The detection unit may detect the audio signal. The alert unit may generate an alert signal in response to the request if the detection unit has not detected the audio signal. It can thus be checked whether the acoustic signal is generated. A method for generating a safety critical acoustic signal is also described.Type: GrantFiled: August 24, 2012Date of Patent: May 2, 2017Assignee: NXP USA, Inc.Inventors: Michael Staudenmaier, Vincent Aubineau, Davor Bogavac

Patent number: 9483856Abstract: A display controller comprising a blending stage and a blending controller. The blending stage is provided for blending multiple image layers into one display output image and comprises a plurality of input channels for receiving pixel data for the multiple image layers. The blending stage further comprises multiple blenders for combining the pixel data received by at least two input channels of the plurality of input channels. The blending controller is coupled to the blending stage for controlling operation of the blending stage. The blending stage further comprises a controllable switch for coupling an output of at least one blender of the multiple blenders to a display output of the blending stage for regular on-the-fly blending or to an offline blending memory for storing a result of an offline blending task.Type: GrantFiled: April 20, 2012Date of Patent: November 1, 2016Assignee: FREESCALE SEMICONDUCTOR, INC.Inventors: Michael Staudenmaier, Vincent Aubineau, Davor Bogavac

Patent number: 9061589Abstract: A display controller includes a controller input connectable to receive first image data representing a non-safety relevant part of an image to be displayed on a display and to receive second image data representing a safety relevant part of the image. A merging unit is connected to the controller input, for composing the image from the first image data and second image data. A controller output is connectable to the display, for outputting display data representing the image. An image monitor is connected to the controller output, for comparing a part of the image corresponding to the safety relevant part with an reference for the part.Type: GrantFiled: May 20, 2008Date of Patent: June 23, 2015Assignee: Freescale Semiconductor, Inc.Inventors: Florian Bogenberger, Davor Bogavac

Publication number: 20080276107Abstract: A method of communication comprising sending communication signals switched between dominant and recessive values at clock intervals in frames over a serial data bus from at least one of a plurality of sending nodes to a plurality of receiving nodes. The receiving nodes have an operational state and a standby state in which the current consumption of the node is reduced compared to the operational state. The receiving nodes include wake-up trigger means for triggering transition from the standby state to the operational state in response to the communication signals.Type: ApplicationFiled: April 26, 2005Publication date: November 6, 2008Applicant: FREESCALE SEMICONDUCTOR, INC.Inventor: Davor Bogavac

Publication number: 20050102430Abstract: A controller node (3-6) for communication with remote nodes (11-25) over a communication bus (1), especially a CAN bus. The controller node comprises a data processing unit (30) for generating signals to be transmitted and for processing signals received over the communication bus (1), and a management unit (31) responsive to event signals from the remote nodes (11-25) and/or from the data processing unit (30) for generating control signals controlling the operating state of the data processing unit (30). The management unit (31) includes a crystal or resonator frequency reference (37), and an oscillator (36) controlled by the reference frequency for generating a clock signal. A clock switch (38) supplies the clock signal to at least a part of the data processing unit (30) during at least a first operating mode of the data processing unit and interrupts supply of the clock signal during a second operating mode of the data processing unit.Type: ApplicationFiled: July 29, 2004Publication date: May 12, 2005Inventors: Yves Huber, Davor Bogavac, Phillipe Mounier
