A tactile stimulus presentation device includes a stage, a contact member, a drive mechanism, an information setting part, and a control part. The stage includes an opening and an arrangement surface, the arrangement surface on which a body part of a subject is arranged thereon so as to close the opening. The contact member is for giving a tactile stimulus to the subject by being in contact with the body part of the subject arranged on the arrangement surface of the stage through the opening. The drive mechanism is a mechanism for holding the contact member and moving the contact member in a direction substantially parallel to the arrangement surface and in a direction substantially perpendicular to the arrangement surface. The information setting part is configured to set information to be presented by gibing tactile stimulation to the subject by tactile stimulation. The control part is configured to control the drive mechanism to present the information set by the information setting part by giving tactile stimulation to the body part of the subject arranged in abutment on the arrangement surface.

A proximity alert system for access badges including a transmitter assembly and a receiver assembly is disclosed herein. The transmitter assembly includes a transmitter housing. The transmitter housing includes a battery compartment. The housing assembly further includes a light to indicate the status of the battery. The housing assembly also includes a transmitter sensor and an adherable side to attach the transmitter assembly to a badge. The receiver assembly includes a receiver housing. The receiver housing includes a battery compartment, a light, a speaker, a motor, a clip and a receiver sensor. The light indicates the status of the battery. The receive sensor communicates with the transmitter sensor. The receiver sensor activates the motor and the speaker if the transmitter assembly and the receiver assembly are far from each other.

[Object] To provide a technology capable of presenting various haptic sensations to a user.

[Solving Means] A haptic presentation apparatus according to the present technology includes: a first deformable layer; a second deformable layer; and a drive unit.

A method may include receiving, by a transducer driving system, a first signal for driving an amplifier that drives an electromagnetic load and receiving, by the transducer driving system, a second signal driven by the amplifier in order to control a feedback loop of the transducer driving system. The method may also include detecting unexpected spectral content in the second signal, declaring an indicator event based on the detected unexpected spectral content, determining whether the indicator event occurs in an undesired pattern, and in response to the indicator event occurring in the undesired pattern, modifying a behavior of the transducer driving system.
