Abstract: In example implementations, a method, a device, and a program are provided. The method includes detecting a power increase movement of a printer carriage. A location of the printer carriage is detected at a time of the detected power increase. Based on the detected location of the printer carriage, determine whether the print medium is damaged. The device includes a power monitor to detect a power increase during movement of a printer carriage. A locator detects a location of the printer carriage at the time of the detected power increase. A damage determiner determines, based on the detected location of the printer carriage, whether the print medium is damaged. The program detects a power increase during movement of a printer carriage. Location of printer carriage is detected at time of detected power increase. Based on detected location of the printer carriage, it is determined whether the print medium is damaged.

Abstract: An example container includes: structure having an interior and an exterior. The interior is to contain an electronic product. The exterior comprises: a first label of a first type of polychromatic ink to be activated at a first wavelength; and a second label of a second type of polychromatic ink to be activated at a second wavelength different from the first wavelength; the first label to indicate a first set of features to be configured at the electronic product using a first wireless signal; and the second label to indicate a second set of features to be configured at the electronic product using a second wireless signal. The structure is transparent to the first wireless signal and the second wireless signal.

Abstract: A PCR kit-of-parts is described. The kit-of-parts comprises a first oligonucleotide bound to a bead by a cleavable linker; a second oligonucleotide bound to a bead by a cleavable linker; and an enzyme bound to a bead by a cleavable linker; wherein the first and second oligonucleotide form an oligonucleotide pair complementary to a nucleic acid of interest and the enzyme is capable of extending nucleic acid strands; and each cleavable linker is independently selected from a photocleavable linker and a thermally cleavable linker. Also described is a method of performing PCR and a PCR system.

Abstract: In some examples, a computer receives an image of a head-mounted user device that is separate from the computer, the head-mounted user device including a display device. The computer determines, based on the image of the head-mounted user device, a position of the head-mounted user device, and based on the determined position of the head-mounted user device, adjusts display content in the display device of the head-mounted user device.

Abstract: In one example in accordance with the present disclosure, an example computing device is disclosed. The example computing device includes a housing. The example computing device also includes a rotatable antenna disposed within the housing. The rotatable antenna is to rotate such that a direction of radiation is maintained in a single direction as the housing is to rotate.

Abstract: An example apparatus may include a hardware component, a memory, and a processor. The processor may retrieve a firmware for the hardware component subsequent to the firmware being loaded on the hardware component. The processor may determine that a firmware signature associated with the firmware is stored in the memory. In some examples, in response to a determination that the firmware signature associated with the firmware is stored in the memory, the processor may initiate authentication of the firmware.
