A pet status assessment system includes an area detector, an information generator, and an assessor. The area detector detects, in image data, a specific area representing at least a part of appearance of a pet as a subject. The information generator generates pet information. The pet information includes posture information which is based on a learned model and the image data. The learned model has been generated by learning the posture of the pet to recognize, on an image, the posture of the pet. The assessor assesses, based on the pet information, a pet status concerning at least one of an emotion of the pet or an action of the pet.

Pet status assessment system, pet camera, server, pet status assessment method, and program

The present invention provides an electrophotosensitive material comprising a conductive substrate and a photosensitive layer provided on the conductive substrate, the photosensitive layer comprising a specific hole transferring material and/or electron transferring material and a binding resin of a polyester resin which is a substantially linear polymer obtained by using a specific dihydroxy compound represented by the general formula (1):

Electrophotosensitive material

The present invention provides a novel naphthylenediamine derivative which is superior in electric charge transferring capability, compatibility with binding resin and stability, and an electrophotosensitive material which has a higher sensitivity and an excellent durability. The above naphthylenediamine derivative is represented by the following general formula (1), and the electrophotosensitive material is formed by providing a photosensitive layer having this naphthylenediamine derivative as an electric charge transferring material on a conductive substrate. ##STR1## wherein R.sup.1 to R.sup.4, R.sup.5a to R.sup.5f and a to d are as defined.

Naphthylenediamine derivative and electrophotosensitive material using

The present invention provides an electrophotosensitive material comprising a conductive substrate and a photosensitive layer provided on the conductive substrate, the photosensitive layer comprising a specific hole transferring material and/or electron transferring material and a binding resin of a polyester resin which is a substantially linear polymer obtained by using a specific dihydroxy compound represented by the general formula (1): ##STR1## wherein R.sup.1 is an alkylene group having 2 to 4 carbon atoms; and R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are the same or different and indicate a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an aryl group or an aralkyl group or the like. This photosensitive material is improved in sensitivity, and is also superior in adhesion to conductive substrate as well as mechanical strength such as wear resistance, etc.

There is disclosed an electrophotosensitive material using a binding resin of a bisphenol C type, bisphenol Z type, bisphenol Z type containing a substituent or bisphenol C-copolymer type polycarbonate in combination with a hole transferring material of a specific benzidine or phenylenediamine derivative. This photosensitive material is superior in mechanical strength and repeat characteristics and has a high glass transition temperature and a high sensitivity.
