A system comprising a processor and a memory comprising firmware is provided. The firmware is executable by the processor to cause the processor to operate a print mechanism in accordance with a first state associated with a capability of the print mechanism, change the first state associated with the capability to a second state in response to receiving first information from an external interface, and operate the print mechanism in accordance with the second state associated with the capability.

Printer with selectable capabilities

A security chip including a fusible logic array. The fusible logic array is configured to receive a plurality of seed values and output a plurality of respective keys using the received plurality of seed values. The respective keys correspond to logic results generated by the fusible logic array. The fusible logic array includes one or more fusible links. A key storage control module is configured to receive the plurality of seed values, receive the plurality of respective keys, and store, in memory, a selected first seed value of the plurality of seed values and a selected first key of the plurality of respective keys. The selected first seed value and the selected first key are stored as a seed-key pair.

Systems and methods for generating and storing silicon fingerprints for a security chip

A system-on-chip including circuit instances, a selector module, a circuit instance module, and a comparing module. The circuit instances have respectively nodes. The circuit instances are designed to provide nominally a same value at each of the nodes. The selector module is configured to generate a selection signal. The circuit instance module is configured to (i) monitor states of the nodes, and (ii) based on the selection signal, select (a) two or more of the states of the nodes, or (b) two or more parameter values generated based on the two or more of the states of the nodes. The comparing module is configured to: compare (i) the two or more of the states of the nodes, or (ii) the two or more parameter values; and based on the comparison, output a bit of (i) a silicon fingerprint of the system-on-chip, or (ii) a unique response code of the system-on-chip.

Systems, methods, and other embodiments associated with using an audio link for authentication services are described. According to one embodiment, an apparatus includes The apparatus includes a processor configured to monitor an audio channel for an authentication signal. The authentication signal is an analog signal provided from a host device over the audio channel to the processor when authenticating the apparatus. The apparatus includes an authentication module configured to generate an authentication response after the authentication signal is detected by the processor. The processor is configured to provide the authentication response as an audio signal on the audio channel to a speaker.

Using an audio channel for authenticating a device

The present disclosure describes apparatuses and techniques for device-based die authentication. In some aspects, an intensity of a particle beam is varied during semiconductor processing to provide a semiconductor die having devices of varied values. In other aspects, different areas of semiconductor dies are exposed during semiconductor processing to provide semiconductor dies with devices that vary in value from one die to the next. For each semiconductor die, a value generated based on the values of the die's respective devices can be associated with that die thereby enabling subsequent authentication of the semiconductor die.

Method and apparatus for authenticating a semiconductor die

A security chip including a fusible logic array. An input is configured to receive, from a verification module external to the security chip, a seed value corresponding to one of a predetermined value and a generated value. The fusible logic array is configured to generate a logic result using the received seed value. The fusible logic array includes a logic gate configured to operate, based on a state of a fusible link within the logic gate, as both a first type of logic gate configured to perform a first logic operation and a second type of logic gate configured to perform a second logic operation different from the first logic operation. The fusible logic array is configured to generate the logic result based on the state of the fusible link. An output is configured to provide a key value, representative of the logic result, to the verification module.

Chip or SoC including fusible logic array and functions to protect logic against reverse engineering

A multifunction image processing apparatus is disclosed. The apparatus includes a communications module, a scan subsystem, a print subsystem, and a digital signal processor (DSP) block. The communications module is used to communicate with a host computer to send and receive image data files. The scan subsystem is used to scan images. The print subsystem is used to print images. The DSP block includes at least two digital signal processors. The digital signal processors can be programmed to symmetrically multiprocess portions of an image data file to process it more quickly. Alternatively, digital signal processors can be programmed to simultaneously process the image data for the scan subsystem and image data for the print subsystem.

Image processing apparatus with symmetric processors

Systems, apparatuses, and methods for a printing device for use with a mobile device are described herein. The printing device may include an image capture module to capture surface images of a medium and a positioning module to determine positioning information based at least in part on navigational measurements and the captured surface images. A print module of the printing device may cause print forming substances to be deposited based at least in part on the positioning information. A mobile device may include one or more features of the printing device including the image capture module, the positioning module, and the print module. Other embodiments may be described and claimed.

Systems, apparatuses, and methods for an image translation device providing navigational data feedback to a communication device are described herein. The image translation device may operate in a navigational feedback mode to transmit navigational data to the communication device or an active image translation mode to generate position data to facilitate an image translation operation. Other embodiments may be described and claimed.

Image translation device providing navigational data feedback to communication device

Systems, apparatuses, and methods for a scanning device for use with a mobile device are described herein. The scanning device may include an image capture module to capture surface images of a medium to be scanned and a positioning module to determine positioning information based at least in part on navigational images and the captured surface images. A mobile device may include one or more features of the scanning device including the image capture module and the positioning module. Other embodiments may be described and claimed.

Handheld scanning device

A multi-function printer having a compact size and portable configuration while providing printing, scanning and copying functionalities is disclosed herein. The multi-function printer includes a printer assembly and a scanner assembly configured to cooperatively utilize the same pick and paper movement systems along a common feed or paper path to perform these printing, scanning and copying functions. Thus, the disclosed multi-function printer may require a less complex paper movement and control system which, in turn, reduces the printer's overall weight while increasing its flexibility and/or portability.
