Abstract

According to the present invention, a single file storing information for displaying a plurality of pieces of three-dimensional object data in the same coordinate system is operated. First data of a first three-dimensional object and second data of a second three-dimensional object different from the first three-dimensional object are acquired. Arrangement information for arranging the first three-dimensional object and the second three-dimensional object in the same coordinate system is generated. Metadata common to the first three-dimensional object and the second three-dimensional object is generated. A first track for managing the first data, a second track for managing the second data, and a third track for managing the metadata are generated. A single file in which the first track, the second track, and the third track, the first data and the second data, the arrangement information, and the metadata are stored is generated.

Abstract

Two or more trust levels are implemented that allow switching between various encryption keys to obfuscate, using a PRF, PE parameters. An ERCM Key specific to each PE client is derived from a KDK forming part of the PTK: ERCM Key = KDF-Hash-256(KDK, "ERCMK", @MAC_Client || @MAC_AP), wherein the KDF-Hash-256 generates the 256 bits key of the ERCMK, @MAC_Client and @MAC_AP are the MAC addresses of the CPE Client and CPE AP used for 4-way Handshake, "ERCMK" is a context string name for ERCM and is treated as an ASCII string. An alternative ERCM Key known by all CPE Clients is a common group temporal key known by all CPE Clients. It is a 256-bits random value shared during the 4-way Handshake and generated by the AP and encrypted by the KEK of the PTK in the message 3 (with GTK, IGTK and BIGTK).

Abstract

A pair of planar surface portions 6 are provided on two opposite outer wall surfaces of a storage container 1 in the vertical direction, in the horizontal direction, or in the front-rear direction when the storage container is in an installed state. A recessed portion 15 is formed in a portion of at least one of the planar surface portions 16, and is formed so as to be recessed inward from another portion 16a of the planar surface portion 16, and such that at least a portion of the recessed part 15 is in communication with the outside of the planar surface portion 16 in a direction along the planar surface portion 16. A relief valve 11 is provided in the recessed portion 15, and automatically opens when the pressure inside a storage portion 14 for storing a hydrogen carrier exceeds a predetermined value, thereby releasing the gas inside the storage part 14 to the outside. This makes it possible to suppress a rise in the pressure inside the storage container 1 for storing a hydrogen carrier or a by-product, even if multiple storage containers 1 are stored stacked in the vertical direction or laid out in the horizontal direction or the front-rear direction.

Abstract

This electronic device has: a diaphragm that comes into contact with an object being measured, the diaphragm being provided with a light reflection part on a surface on the side opposite from the contact surface of the diaphragm that comes into contact with the object being measured; a light-emitting diode; a throttling part for throttling light emitted from the light-emitting diode; a light-receiving element having a light-receiving surface for receiving light that passes through the throttling part and is regularly reflected by the light reflection part; an output unit for outputting a signal corresponding to light in a light irradiation region formed by the regularly reflected light reaching the light-receiving surface; and a housing for accommodating the light-emitting diode, the throttling part, and the light-receiving element therein. The diaphragm is configured so as to form, together with the housing, a portion of the exterior of the electronic device, and to elastically deform upon being pressed by the object being measured in contact with the contact surface. A boundary line between the light irradiation region and a region other than the light irradiation region on the light-receiving surface, the boundary line being formed by the light that has been throttled by the throttling part and regularly reflected by the light reflection part, moves in accordance with displacement of the contact surface caused by the elastic deformation of the diaphragm, whereby the area of the light irradiation region on the light-receiving surface changes and the output of the output unit changes.

Abstract

The present invention uses a cartridge that comprises: a photosensitive drum; a development roller; a supply roller; a development chamber; a development blade that includes an elastic blade and a support section; and an accommodation section for a toner that has a particle diameter R. The accommodation section and the development chamber are in mutual communication. A site of contact between the development blade and the development roller is below a horizontal line that passes through the center of the axis of rotation of the development roller. Fluorine is present in the interior of hydrotalcite particles of an external additive of the toner. If, in a nip of the elastic blade and the development roller, an end section on the upstream side in the direction of rotation of the development roller is a point D, the furthest free-end side of the elastic blade is a point B, a point where a line perpendicular to the point B intersects the development roller is a point E, a point on the furthest free-end side among points on the surface of the elastic blade at a distance R from the surface of the development roller is a point F, and a point on a line BE at the distance R from the surface of the development roller is a point G, then the distance between the points G and F is at least R.

Disclosed are an image recording device and an image recording method with which it is possible to relax restrictions on the length of a pre-recording period. The image recording device is capable of performing pre-recording, in which recording of an image captured by an imaging unit is started prior to the start of actual recording. When a start condition for the actual recording is satisfied while pre-recording is being executed, the image recording device starts the actual recording of the image captured by the imaging unit. The image recording device performs the pre-recording onto a non-volatile recording medium to be used for the actual recording.

The method comprises: decoding a first tensor from the bitstream: deriving a second tensor by performing at least a first convolutional layer on the first tensor; and deriving successive tensors based on the second tensor, each successive tensor being derived from a current tensor by summing a result of performing a convolutional layer on the current tensor and a result of down-sampling of the current tensor, such that each successive tensor has smaller spatial size than the current tensor. The derived second tensor and the successive tensors form the hierarchical representation, the second tensor is used as the current tensor in deriving a first of the successive tensors and each derived successive tensor is used as the current tensor in deriving the next successive tensor

Abstract

To reduce OBSS interference, a neighbouring AP in a MAP coordination set of APs receives, from a target AP managing a target BSS, a MAP coordination frame specifying a TWT schedule provided in the target BSS. The neighbouring AP defines an OBSS TWT schedule having TWT SPs at least partially overlapping with TWT SPs of the TWT schedule in the target BSS. The OBSS TWT schedule forbids the stations of the neighbouring BSS to access the wireless medium during the OBSS TWT SPs. Alternatively, it defines reduced communication activities for those stations during the OBSS TWT SPs, by setting an OBSS EDCA Parameter Set to be used. In a further alternative, it indicates a temporary operating channel for stations of the neighbouring BSS to switch to the temporary operating channel for their communications during the OBSS TWT SPs.
