Abstract: Technology is described for generating 3D spatial mappings. One operation may be receiving a 2D image of patient anatomy from a medical imaging device. Another operation may be identifying a placement of an imaging device in a 3D coordinate system of an augmented reality (AR) headset when capturing the 2D image. A graphical mark may be received from a user for a point within a body of a person in the 2D image. A 3D coordinate of the point in the 3D coordinate system may be computed using the position and orientation of the imaging device with respect to the AR headset and a depth of the point, in order to generate a 3D spatial mapping.

Abstract: According to an embodiment of the present invention, a method for using information in conjunction with a data repository includes encrypting data associated with the information with an encryption key, sending at least the encrypted data to the data repository, and possibly deleting the information. The method also includes receiving a request for the information from a remote device, and sending a request for the encrypted data to the data repository. The method further includes receiving the encrypted data from the data repository, decrypting the encrypted data using the encryption key, and sending the information to the remote device.

Abstract: A technology is described for aligning an image data set with a patient using an augmented reality (AR) headset. A method may include obtaining an image data set representing an anatomical structure of a patient. A two-dimensional (2D) X-ray generated image of at least a portion of the anatomical structure of the patient in the image data set and a visible marker may be obtained. The image data set can be aligned to the X-ray generated image by using data fitting. A location of the visible marker may be defined in the image data set using alignment with the X-ray generated image. The image data set may be aligned with a body of the patient, using the visible marker in the image data set as referenced to the visible marker seen on the patient through the AR headset.

Abstract: A retainer assembly includes a retaining member assembly and a motion assembly. The retaining member assembly is structured to selectively retain at least one shell in a transfer belt assembly belt recess. The retaining member assembly includes a retaining member. The motion assembly is structured to move the retaining member between a first position, wherein the retaining member is spaced from the transfer belt assembly transfer belt, and, a second position, wherein the retaining member is disposed a retaining distance from the transfer belt assembly transfer belt.

Abstract: A method for disabling a device associated with a virtual identity may include receiving, from the device, a request to use the virtual identity, where the request that may include a passcode guess and a device identifier. The method may also include determining that the passcode guess does not authorize use of the virtual identity and incrementing a number of incorrect passcode guesses received within a time interval. The method may additionally include determining that the number of incorrect passcode guesses received within the time interval is greater than or equal to a threshold. The method may further include storing an indication that subsequent requests associated with the device identifier should not authorize use of the virtual identity.

Abstract: A system and method of additively manufacturing a part via salt micro-spheres. The method includes mixing salt micro-spheres with an additive manufacturing material to form an additive manufacturing material mixture. The additive manufacturing material mixture is deposited on a build platform layer by layer and cured so as to create a structure having pores formed by the salt micro-spheres. The salt micro-spheres may then be dissolved and flushed from the pores.

Abstract: A material handling apparatus for reorienting and transferring inventory items to a packaging device includes a support member and a packaging conveyor. The support member receives an inventory item and reorients the item to a rejection orientation or a packaging orientation. The item is moved onto the packaging conveyor in the packaging orientation and is transported to the packaging device.

Abstract: The purpose of this device is to reduce the fuel consumption of heavy trucks by improving airflow past trailer axles. Rather than restrict airflow to the side of the vehicle, diffusers streamline its aerodynamic profile and allow air to flow smoothly beneath. A series of panels mounted to each axle of a truck and trailer forms a substantially continuous surface from the front to the rear axle, promoting laminar flow to the aft of the vehicle, minimizing the effect of suction drag.

Abstract: A tool for feeding material into a mill having a roller and forming a nip gap. The tool broadly comprises a baseplate, a guide plate, and a ram. The baseplate is configured to be positioned on the mill over the roller and forms a slot. The guide plate is configured to be positioned in the slot of the baseplate near the nip gap. The guide plate forms a chute for feeding the material into the nip gap. The ram is configured to be inserted into the chute to urge the material into the nip gap while preventing a user's fingers and other foreign objects from nearing the nip gap through the chute.

Abstract: A glide rack assembly removably installable within a cooking chamber. The assembly includes a support rack, an engagement member extending downward therefrom and being translatable between a fully retracted position and an extended position, and a locking arm. The locking arm is configured such that when the support rack is in the fully retracted position, the engagement member deflects said locking arm into an unlocked position wherein the locking arm does not cooperate with an embossment on a side wall of the cooking chamber. Further, when the support rack is translated from the fully retracted position, the engagement member does not deflect the locking arm such that the locking arm pivots to a locked position wherein the locking arm cooperates with the embossment such that the assembly is inhibited from being removed.

Abstract: A technology is described for using an augmented reality (AR) headset to co-localize an image data set with a body of a person. A method may include registering one or more initial visible markers attached to the body of the person, and the optical code may be located in a fixed position relative to the image visible marker. The coordinate system of the one or more initial visible markers may be transferred to the one or more additional visible markers. The use of the one or more additional visible markers may be emphasized to align of the image data set with the body of the person.

Abstract: Technology is described to adjust for eye location variations of a user when using an augmented reality (AR) headset. The method can include registering a position and size of an optical code using a visual camera and the AR headset. An alignment marker may be projected through the AR headset to be aligned with the optical code for a right eye and left eye of a user of the AR headset. Right eye and left eye adjustments to the alignment marker may be received independently to align the alignment marker with a portion of the optical code as viewed by either the right eye or left eye of the user. The left eye adjustments and right eye adjustments may be applied to virtual images displayed through the AR headset in order to improve the accuracy of alignment between objects in the physical view and the virtual images displayed using the AR headset.
