Abstract: A fluid thermal processing device may include a substrate, a platform projecting from the substrate, a fluid heating element supported by the platform, a temperature sensing element, distinct from the fluid heating element, supported by the platform and an enclosure supported by and cooperating with the substrate to form a fluid chamber about the platform. The fluid chamber forms a volume of uniform thickness conforming to and about the platform.

Abstract: In an example implementation according to aspects of the present disclosure, a system comprises a display device, a gaze tracking device, and processor operatively coupled with a computer readable storage medium and instructions stored on the computer readable storage medium that, when executed by the processor, direct the processor to display, by the display device, a pattern of images to a user; capture, by the gaze tracking device, involuntary eye movements of the user viewing the pattern of images on the display device; and authenticate the user based on the involuntary eye movements of the user matching a stored user preference information.

Abstract: In one example in accordance with the present disclosure, a fluid ejection device assembly is described. The fluid ejection device assembly includes a monolithically molded fluidic structure to extend between a separately molded body comprising a print fluid reservoir and a fluid ejection device. The fluidic structure includes a plenum to receive a print fluid from the body at a fluidic interface.

Abstract: That content on a last page of a print job having multiple pages satisfies a residue threshold is detected. In response to detecting that the content on the last page satisfies the residue threshold, the print job is modified to have one fewer page. A printing device is caused to print the modified print job.

Abstract: In an example implementation according to aspects of the present disclosure, a system receives behavioral biometric data associated with a user of a computing device. The system determines whether an identity of the user is authenticated based on a comparison of the received behavior biometric data and historical behavioral biometric data associated with the user of the computing device. In response to determining that the identity of the user is not authenticated based on the comparison of the received behavioral biometric data and the historical behavioral biometric data, the system receives physiological biometric data associated with the user. The system determines whether the identity of the user is authenticated based on a comparison of the received physiological biometric data and historical physiological biometric data associated with the user of the computing device.

Abstract: The present disclosure is drawn to powder bed materials. The powder bed material can include from 20 wt % to 95 wt % of a large particulate metal and from 5 wt % to 80 wt % of a small particulate metal. The large particulate metal can have a D50 particle size distribution value ranging from 20 μm to 100 μm and an average aspect ratio from 1:1 to 1.1:1. The small particulate metal can have a D50 particle size distribution value ranging from 1 μm to 15 μm and an average aspect ratio from greater than 1.1 to 2.1.

Abstract: A radio frequency (RF) tamper detector of an electronic device can offer improved chassis intrusion monitoring to protect the device from software and hardware-based tampering. The tamper detector can monitor RF noise levels in a first frequency band and in a second frequency band to calculate an RF noise level moving average for each frequency band. If the moving averages in both frequency bands exceed a RF noise threshold, the tamper detector can set a cover removal flag to indicate that a cover of the device housing has been removed. The tamper detector can cause the electronic device to lock or disable a system BIOS when cover removal is detected. Additionally, the electronic device can notify remote monitoring systems (e.g., operated by an IT administrator or warranty support center) to receive additional instructions to secure the device.

Abstract: A fluidic die including an array of fluid actuating devices addressable by a set of addresses, and an array of memory elements including a first portion to receive a first set of address bits representative of a first portion of an address of the set of addresses, and a second portion to receive a second set of address bits representative of a second portion of the address of the set of addresses. A first address driver is to provide a first portion of the address of the set of addresses based on the first set of address bits received by the first portion of memory elements, and a second address driver is to provide a remaining portion of the address of the set of addresses based on a second set of address bits received by the second portion of memory elements.
