A portable security device may enable a security guard to quietly and unobtrusively solicit assistance, or transmit information, when desired. A portable security device may include a user interface, a LiFi source and a controller that is operatively coupled to the user interface and to the LiFi source. In some cases, the controller may be configured to present two or more alert options to the security guard via the user interface and to receive a selection of one of the alert options by the security guard. In response to the selection of an alert option by the security guard, the controller may be configured to transmit a LiFi message that corresponds to the selected alert option via the LiFi source.

An image forming apparatus includes a hardware resource, and a hardware processor that controls the hardware resource, wherein the hardware processor activates the hardware resource in a first activation mode in response to entry of a user into a first range, and activates the hardware resource in a second activation mode that causes production of sound at a volume level higher than a volume level of sound produced in the first activation mode in response to entry of the user into a second range that is smaller than the first range.

A shared terminal includes: circuitry to cause a display to display an image to a plurality of users, the plurality of users simultaneously sharing use of the shared terminal; and a network interface to communicate with a destination management server through a network, the destination management server being different from the shared terminal and storing, in a memory, for each of the plurality of users, user identification information of the user in association with an email address of the user. The circuitry: obtains, from a first terminal of a first user of the plurality of users, first terminal identification information identifying the first terminal; transmits first user identification information of the user of the first terminal to the destination management server; receives, from the destination management server, a first email address of the first user, the first email address being obtained from the memory of the destination management server using the first user identification information; and transmits an email addressed to the received first email address to allow the first user to obtain data relating to the image displayed to the plurality of users.

Examples disclosed herein relate to providing access to digital content using a machine-readable link. As an example, an annotation comprising digital content, for a portion of a digital content, is identified in response to a print request. Based on the annotations, a machine-readable link associated with the digital content is generated. Subsequently, a printable format version of the digital document comprising the machine-readable link, and excluding the annotation is obtained wherein the machine-readable link is readable by a computing device to obtain access to the digital content over a communication network.

An electronic device and an image capturing apparatus are provided. The electronic device includes: a fixing apparatus, adapted to, in a case that a user wears the electronic device, maintain a position relationship between the electronic device and at least part of body of the user; an image capturing apparatus having an image capturing area, adapted to capture an image in the image capturing area; a data transmission apparatus, adapted to, in a case that a data connection is established between the electronic device and a second electronic device, perform data transmission with the second electronic device; an audio output apparatus having an audio output area, adapted to output sound to the audio output area; and a processing apparatus, adapted to control at least one of the image capturing apparatus, the data transmission apparatus and the audio output apparatus, wherein the electronic device comprises no image displaying apparatus.
