A keyboard apparatus according to an embodiment includes a keyboard and a mutual capacitance proximity sensor. The keyboard includes a first key and a second key arranged in an array direction with respect to the first key. The proximity sensor includes a first electrode having a portion extending from at least a first area below the first key to a second area below the second key, a second electrode arranged in the first area, and a third electrode arranged in the second area. The proximity sensor is a mutual capacitance type sensor and is configured to use a change in capacitance between the first electrode and the second electrode and a change in capacitance between the first electrode and the third electrode.

A speech providing device includes a memory that stores instructions, and a processor that executes the instructions. The instructions cause the processor to perform acquiring a position of a user and a direction that the user is facing, and providing a speech corresponding to an area existing in a direction that the user is facing on the basis of the position of the user, to the user.

Provided is a technology for allowing only a wireless terminal satisfying a security policy to be connected to an in-company network without causing a significant increase in costs. The terminal management device including a determination part communicating with a wireless terminal via a different communication network from the wireless network system, and determining whether or not the wireless terminal satisfies a predetermined security policy, and a connection information transmission part transmitting connection information for connection to the wireless relay device to the wireless terminal which is determined to satisfy the security policy by the determination part is provided in a wireless network system that includes a wireless access point device constituting an in-company network and connecting a wireless terminal for which predetermined connection information has been set.

Provided is a communication device for measuring a usable bandwidth without delay in transmission of primary data. The relay device according to an embodiment of the present invention, when measuring a usable bandwidth in communication with another relay device, processes a user packet including a user data to be transmitted to the other relay device so as to be changed into a specific packet size while the user data is maintained as it is, and utilizes it as a measurement packet. Accordingly, even though it is a measurement packet for performing measurement of a bandwidth, since it includes user data, it may be treated in the same manner as a user packet thereby enabling an efficient use of a communication network in communication. Also, even though UDP is used, since a usable bandwidth can be measured, it is possible to measure a bandwidth even though streaming data is distributed while preventing any influences on the distribution.
