In example implementations described herein, there is a smart hat that is configured to receive gesture inputs through an accelerometer or through touch events on the hat, with light emitting diodes providing feedback to the wearer. The smart hat can be configured to be connected wirelessly to an external apparatus to control the apparatus by transmitting and receiving messages (e.g., commands) between the hat and the apparatus wirelessly. Further, a network of smart hats may be managed by an external device depending on the desired implementation.

Smart hat device for interacting with remote devices and displays

A method of controlling access to an enclosed area having a boundary includes generating a first inaudible audio signal inside the enclosed area, and generating a second signal, each configured to be sensed by a sensing device, wherein the first inaudible audio signal is not capable of penetrating the boundary; determining a state of the enclosed area, based on either the first inaudible audio signal, or the first inaudible audio signal and the second signal, being sensed by the sensing device; and based on the state, generating an instruction to perform access control for the enclosed area.

System and method of access control for spaces and services

A particle dispersion and the display devices in which the dispersion may be incorporated are provided. The particle dispersion includes a dispersion medium, one or more types of particle groups that are dispersed in the dispersion medium that may differ based on color and/or charge, and counter-ions oppositely charged than the one or more particle groups. The particle groups and counter-ions are moved in the dispersion medium according to an electric field formed in the dispersion medium. The one or more types of particle groups are configured such that the total amount of charges of one type of particle group (a) among the one or more types of particle groups is greater than a total amount of charges of the counter-ions that are charged with a polarity opposite to that of the particle group (a).

Particle dispersion for display, display medium, and display device

A particle dispersion for display includes color particles for display that move in response to an electric field and include first color particles and second color particles; and a dispersion medium that disperses the color particles for display, in which the second color particles have a larger particle diameter than a particle diameter of the first color particles and the same charging characteristic as a charging characteristic of the first color particles, and in the color particles for display, a ratio (Cs/Cl) of a charge amount Cs of the first color particles per unit area of display to a charge amount Cl of the second color particles per unit area of display is less than or equal to 5.

Electrophoretic particles including mother particles and a dispersant that covers the surface of the mother particles, the mother particles including a resin and a colorant, and the dispersant having a structure represented by the following Formula (1): 

Electrophoretic particles, electrophoretic particle dispersion, display medium and display device

A particle dispersion for display including: first particles for display including a colorant and a first polymer having a first charging group, the first particles for display being movable in response to an electric field; a first polymeric dispersant attached to the first particles for display; second particles for display including a colorant and a second polymer having a second charging group, the second particles for display being movable in response to an electric field; a second polymeric dispersant attached to the second particles for display; and a dispersing medium in which the first particles for display and the second particles for display are dispersed, the first polymeric dispersant and the second polymeric dispersant having different weight average molecular weights so that the first particles for display and the second particles for display start moving upon application of different voltages.

Particle dispersion for display, display medium and display device

An electrophoretic particle dispersion including: electrophoretic particles including first particles having a surface thereof covered with a curvature-adjustment portion formed from a curvature-adjustment material, a curvature at the surface of the curvature-adjustment portion being greater than the curvature of the first particles that do not include the curvature-adjustment portion; a crosslinking agent capable of binding the electrophoretic particles via a reversible crosslinked structure; and a dispersing medium in which the electrophoretic particles and the crosslinking agent are dispersed.
