controlling presentationThe more effective presentation of informational content on display terminals are described within U.S. Patent No. 9224037, titled Apparatus and Method for Controlling Presentation of Information Toward Human Object. The information processing apparatus claimed here includes a memory communicating with a processor to provide a recognition unit that recognizes a human object in captured image data, an identification unit that identifies the human object, an estimation unit that estimates a degree of interest in the human object for obtaining information, an acquisition unit that acquires information to be presented to the human object, a generation unit that generates information to be displayed and a control unit that causes an output unit to output generated information. This invention enables push-type information presentation terminals to present information in a way that reflects a person’s degree of interest in reading information.

 

Patent Applications of Note: From Photoacoustic Imaging to Biomass Electronic Components

acoustic waveTaking a look at Canon’s recently filed patent applications, we found a number of very intriguing imaging technologies such as the photoacoustic technology laid out within U.S. Patent Application No. 20150369651, which is titled Acoustic Wave Acquiring Apparatus and Control Method Therefor. It would protect an acoustic wave acquiring apparatus having an array light source with a plurality of elements that emit measurement light, a controller that controls a wavelength of the measurement light for each element, a Fabry-Perot interferometer including a first mirror upon which the measurement of light is incident and a second mirror upon which an acoustic wave from a subject is incident, an optical sensor that measures a quantity of reflected light produced by the reflection of the measurement light by the mirrors and a processor that acquires an intensity of the acoustic wave based on a change in the quantity of reflected light. This invention is intended to address a shortcoming in photoacoustic imaging devices used in medical fields when variations occur in the polymer film thickness. An invention designed to reduce noise in radiation imaging is featured within U.S. Patent Application No. 20150378034, titled Radiation Imaging Apparatus, Driving Method for the Same, and Non-Transitory Computer-Readable Medium. The radiation imaging apparatus claimed here includes a plurality of sensors and a driving unit to drive those sensors, each sensor having a radiation detection element, a sampling unit that samples a signal from the detection element and a reset unit that initializes the detection element; the driving unit performs a number of output, reset and sampling operations. This technology is advantageous in preventing noise causing unevenness in a radiation image when a frame rate is increased.

A printing composition that exhibits excellent environmental stability is at the center of U.S. Patent Application No. 20150361205, entitled Method for Manufacturing Resin Particles and Method for Manufacturing Toner Particles. It discloses a method for manufacturing resin particles containing a resin having an ionic functional group and a target acid dissociation constant (pKa), the method involving producing the resin particles by using a liquid which is prepared with the resin, an organic solvent to dissolve the resin, water and a neutralizer in an amount effective for neutralizing a certain amount of ionic functional groups. The resulting toner particles have good characteristics for maintaining charge stability in high humidity environments.

Technologies for conducting financial transactions have been cropping up all over the tech world so it’s perhaps not too surprising to see Canon filing U.S. Patent Application No. 20150372993, filed under the title System and Method for Processing Transactions. The method that would be protected involves receiving a request to access a web page including elements for receiving sensitive information when displayed, generating a security token including information for determining whether the token is expired and sending to the web page the security token embedded in that page, which is sent to another server through an inline frame. This innovation is designed to streamline the practice of processing transactions when multiple payment processing systems, including e-commerce systems, are utilized.

polymer compoundsCanon is not typically considered a major innovator in plastics manufacturing, which is why we were piqued to see U.S. Patent Application No. 20160002395, entitled Polymer Compound and Method of Synthesizing the Same. It would protect a liquid vessel comprising a molded article comprised of a particular polymer compound and a liquid contained by the molded article. The invention results in a plastic developed from renewable biomass sources which has improved mechanical strength for applications in electric and electronic components.

This digital camera maker is still focused on developments in film, albeit not always for photography, as is evidenced by U.S. Patent Application No. 20150367613, which is titled Porous Film. It claims a porous film having a first layer made of a porous fluororesin at a thickness of 20 micrometers or less and a water resistance; a second layer of the film which maintains an average distance between local peaks. This invention is meant to overcome issues in film used to filter dust from a gas or liquid, which can be affected by film deformation or a decrease in air permeability.

image sendingFinally, we know that Canon is heavily invested in image capturing but we noted an interesting technology in the field of image sending found within U.S. Patent Application No. 20160011822, entitled Image Sending Apparatus and Authentication Method in Image Sending Apparatus. It discloses an image sending apparatus having memory devices storing instructions executable by processor to receive a password, perform processing for first authentication using the password to allow to set a sending method from multiple options, store the password upon successful authentication, set a destination for sending the image data based on the sending method, determine whether to use a stored password as a password for a second authorization required to send the image and processing the second authorization with or without the stored password based on the determination. The technology results in an efficient method for authenticating a user who is attempting to send an image to a shared network folder that has password security measures.
