Abstract: Described are methods and techniques of a payment card, including: a first layer; a second layer comprising a window of a translucent material; an actuator; and an information layer between the first layer and the second layer, including: a channel comprising an information, wherein the information is biased toward the first layer; and a passage that communicates the channel with the actuator, wherein a fluid is provided in the channel and in the passage such that when the actuator is depressed, fluid flows into the channel via the passage and presses the information against the window making the information visible through the window, and when the actuator is released, the fluid flows out of the channel making the information invisible through the window.

Abstract: One embodiment of the present invention sets forth a technique for providing awareness of privacy-related activities. The technique includes determining a privacy level associated with a user of an extended reality environment. The technique also includes presenting, using an internal display of a headset, one or more internal indicators identifying a location of a bystander located in a real-world environment, wherein a level of detail of each internal indicator is based on the privacy level associated with the user. The technique further includes presenting, using an external display, one or more external indicators that include a monitoring indicator representing being captured by the headset and presented to the user via the headset, and further include a user activity indicator representing one or more activities of the user, wherein a level of detail of the user activity indicator is based on the privacy level associated with the user.

Abstract: A method may include: a policy control computer program receiving, from a headset, an anchor identifier for an anchor in response to the headset being proximate to the anchor; (2) the policy control computer program identifying an area in which the headset is located by retrieving the area mapped to the anchor identifier in a mapping of a plurality of anchor identifiers to a plurality of areas; the policy control computer program identifying a streaming policy for the area, wherein the streaming policy restricts audio and/or video streaming from the area, allows audio and/or video streaming from the area, or restricts audio and/or video streaming from the area; the policy control computer program sending, a control signal to the headset based on the streaming policy; and the headset implementing the control signal to control streaming of audio and/or video to the policy control computer program.

Abstract: Payment cards with activated information displays are disclosed. In one embodiment, a payment card may include: a first layer; a second layer comprising an elastic material; an actuator; and an information layer between the first layer and the second layer, comprising: a plurality of information voids; and a microfluidic channel that communicates the plurality of information voids with the actuator. A fluid may be provided in the microfluidic channel such that when the actuator is depressed, fluid flows into the information voids making the information voids visible through the second layer, and when the actuator is released, the fluid flows out of the information voids making the information voids substantially invisible through the second layer.

Abstract: Method and systems for obtaining direct feedback from a payment card by using energy received from a radio frequency identification (RFID) card reader is provided. The method is implemented by a processor that is embedded in the payment card. The method includes: receiving, from the RFID card reader, a radio frequency (RF) signal that relates to a proposed transaction; transmitting, to the RFID card reader, account information that relates to the proposed transaction; and causing an actuator that is embedded in the payment card to actuate a feedback action based on the RF signal. The actuator may include a haptic device that generates a vibration that is detectable by a touch of a user of the payment card.

Abstract: Methods for creating semolina flour-based shape-changing food from a multi-layered dough with at least one grooved surface. The dough layers have difference compositions including natural, staple and edible ingredients. The dough is exposed to stimuli during dehydration (e.g., baking) or hydration (e.g., boiling) processes.
