Title: Caller protected stack return address in hardware managed stack architecture
Inventor: MICHAEL KARL GSCHWIND
IPC: G06F21/52
Filed: 2016-12-23
Abstract: Corruption of program stacks is detected by using guard words placed in the program stacks. A called routine executing on a processor checks a guard word in a stack of a calling routing. The checking determines whether the guard word has an expected value. Based on determining the guard word has an unexpected value, an indication of corruption of the stack is provided. Some routines, however, may not support use of guard words. Thus, routines that are interlinked may have differing protection capabilities. A determination is made as to the differing protection capabilities, an indication of the same is provided, and the routines are executed without failing due to the differing protection capabilities.

Title: Temperature sensing induction heating tool
Inventor: ANTONIOS CHALLITA
IPC: H05B6/14
Filed: 2017-06-29
Abstract: An induction heating tool that holds voltage or current supplied to the induction tank circuit constant and tracks changes in the other of voltage or current during each induction heating cycle. The disclosed induction heating tool exploits the fact that the resistance an attachment plate increases along with the temperature of the attachment plate. During an induction heating cycle, the attachment plate is magnetically coupled to a work coil and the resistance of the attachment plate is reflected to the circuit. Changes in the resistance of the attachment plate alter the pattern of energy delivery from the work coil to the attachment plate in a predictable way. Calculations accurately predict the temperature of the attachment plate over a wide variety of ambient conditions, including the presence of moisture at the membrane/attachment plate interface. The disclosed induction heating tool produces consistent results without calibration for ambient conditions.

Title: Apparatus configured to produce an image charge/current signal
Inventor: Alexandr Rusinov
IPC: H01J49/42
Filed: 2019-07-10
Abstract: An image current detector is configured to obtain an image charge signal representative of trapped ions undergoing oscillatory motion in an electrostatic ion trap. For ions of a given mass to charge ratio m, the image charge signal in the time domain repeats at a frequency fsig(m) with a signal period Tsig(m). One or more pickup electrodes of the image current detector are arranged to detect two signal pulses caused by ions having the given mass to charge ratio m within each signal period Tsig(m). The pickup electrodes are positioned such that the time separation Δtsep(m) between the two signal pulses caused by ions having the given mass to charge ratio m within each signal period Tsig(m) is approximately equal to [2p+1]/[2.n.fsig(m)], wherein n ≥ 1 and p ≥ 0, and n and p are integers. By carefully spacing the pickup electrodes, the predetermined nth harmonic within the image charge signal can be suppressed or eliminated without complex computational steps.

Title: Provision of digital content via a communication network
Inventor: PETER WILLIS
IPC: H04L29/08
Filed: 2020-01-09
Abstract: A method is disclosed for enabling digital content from a content provider, such as a Content Delivery Network (CDN) operator 14, to be provided from intermediate digital content stores, which may be CDN caches 16, to a user device 18. The provider provides content, encrypted with a public encryption key of a key-pair s20, to an intermediate content store s22. When the user device requests the content, the provider and user device share s23 a session key sk_u, possibly as part of a Transport Layer Security (TLS) handshake. The provider then generates s24 a re-encryption key sk_tx in dependence on a decryption key and the private key associated with the public encryption key, possibly using a cryptographic convolution and a homomorphic function, such that content encrypted with key pk_o and then re-encrypted using sk_tx can be decrypted using the decryption key. The provider provides sk_tx and indications of the requested content to the intermediate store s25, which enables the intermediate store to re-encrypt the content s26 and pass it on to the user device s27. The decryption key, with which the user device may decrypt the content s28, is the session key sk_u, thus avoiding another key exchange process.

Title: Instruction set architecture and microarchitecture for early pipeline re-steering using load address prediction to mitigate branch misprediction penalties
Inventor: SAURABH GUPTA
IPC: G06F9/38
Filed: 2021-08-20
Abstract: Methods and apparatus relating to Instruction Set Architecture (ISA) and microarchitecture for early pipeline re-steering using load address prediction to mitigate branch misprediction penalties are provided. Decode circuitry decodes a load instruction (e.g. Figure 3A) including an indication of whether a branch operation dependent on a load operation of the load instruction is a candidate for prediction, and Load Address Predictor (LAP) circuitry (402 in Figure 4) issues a load prefetch request to memory for data for a load operation of the load instruction. Compute circuitry executes an outcome for a branch operation of the load instruction based on the data from the load prefetch request. Re-steering circuitry transmits a signal to cause flushing of data associated with the load instruction in response to a mismatch between the outcome for the branch operation and a stored prediction value for the branch.
